$100 PCP
The PCP is built on a Crosman 2100B chassis.

I bet that when some people heard about this experiment, they laughed it off. Perhaps that will change now that we have looked at this novel idea 5 different times. I’m learning so much from this series that it’s going to affect my writing for years to come.

I was surprised — again!
Somebody — I don’t remember who — asked me to test the $100 PCP with round lead balls — I guess because the steel BB test turned out so well. So I did. I shot it at 10 meters with .177-caliber Gamo round lead balls. Since I shot with open sights, I didn’t get to see the group after confirming that the first shot hit the paper. Imagine my surprise to see all 10 shots clustered tightly in 0.561 inches!

$100 PCP 10 meters round ball
This tight group really surprised me! Ten .177 Gamo lead balls went into 0.561 inches at 10 meters.

That got me thinking — a lot! I’ve been doing this experiment so slow that I forget what I’ve done before.

What I thought I would do today was complete this report with a test of the rifle scoped at 25 yards. However, when I mounted the scope, it was very far off line, as in angled to the barrel. Either the grooves on the receiver are off or the scope mount I chose wasn’t grabbing the base correctly.

After missing the target twice at 25 yards, I pulled the scope off the rifle and decided to shoot another test with open sights. I used different pellets than I used in Part 4 so we get to see some different results.

Crosman Premier heavy
The first pellet I tried was the 10.5-grain Crosman Premier heavy. In .177, Premiers come in both lite and heavy, and this is the first time I’ve tested this rifle with the heavy. I would love to tell you these pellets went into a small group, but the truth is that they scattered in a 2.352-inch pattern.

$100 PCP 25 yards Crosman Premier heavy
Not particularly encouraging, 10 Premier heavies made this 2.352-inch group at 25 yards.

H&N Baracuda Match
Next, I tried 10 H&N Baracuda Match pellets. They made a better group than the Premier heavies, but it still wasn’t worth talking about. Ten pellets went into 2.051 inches at 25 yards.

$100 PCP 25 yards HN Baracuda Match
Ten H&N Baracuda Match pellets went into 2.051-inches at 25 yards. Still no cigar.

After looking at the second group, I noticed that it looked like the first group, only a little smaller. Because I always look through the spotting scope after the first shot of every group to make sure I’m on paper, I knew that the first shots of both groups were high and right. It seemed to me that the shots might be spreading out to the left as the pressure in the reservoir dropped; so on group 3, I took a photo after the first 5 shots had been fired.

RWS Superdome
Finally I tried RWS Superdomes. Including the lead balls I shot at 10 meters, this was the fourth projectile in this test and the seventh diabolo pellet tested at 25 yards in this rifle. The other 3 pellets were documented in part 4.

$100 PCP 25 yards 5 RWS Superdomes
Five RWS Superdomes made this 5-shot group at 25 yards. Would the next 5 shots spread to the left?

Ten Superdomes went into 1.528 inches at 25 yards. That was the best group in this test with pellets, but only the third best pellet of the seven that were tested at 25 yards.

As it turned out, the next 5 shots didn’t open the group that much more. So, another theory bit the dust.

$100 PCP 25 yards RWS Superdomes
Ten RWS Superdomes made this 1.528-inch group at 25 yards. It’s only a little larger than the first 5 shots, shown above.

Evaluation
The $100 PCP is very accurate at close range, but not as good as the distance increases. Of course, you must remember that the barrel is taped to the reservoir with Gorilla tape, so there’s a lack of precision in the build.

It would still be interesting to see how this rifle behaves when scoped, but I’ll have to find mounts that permit mounting a scope to the integral rail. At this point, I think the $100 PCP is a proven concept. I would really like to see this rifle in production.

See All Open Sight: Part 3

See All Open Sight
The See All Open Sight is revolutionary!

Today, I’m testing the See All Open Sight on the new TX200 Mark III that I’ve been testing for you. Because that rifle figures into today’s test so much, I felt it was important that you be able to examine the rifle’s accuracy in past tests — most importantly, the red dot sight test I just did in Part 13.

I also want to mention that See All is aware of the difficulty in mounting their sight on a straight-line rifle like the M4. They even mention it in the frequently asked questions on their website. So, what happened the last time I tested this sight was my fault for not checking all the information.

Mounting the sight
The first step was to mount the See All sight to the TX200. Since the rifle has 11mm dovetails and the See All has Weaver-width dovetail jaws, I used a prototype Leapers base that converts 11mm to Weaver/Picatinny. For this test, I used the same scope stop pin that I showed in the last test with the dot sight. The pin popped out of the hole on the first shot, so the base had to be remounted and the pin locked down again. After that, the base remained tight and solid throughout the test.

See All Open-Sight-mounted-on-TX-200
The See All Open Sight is mounted on a prototype Leapers 11mm-to-Picatinny base that has a built-in droop (correction for the barrel pointing downwards).

The base of the See All sight has no locking crosspins like those found on a Weaver or Picatinny sight. It has 2 vertical screws that bear down on the sight base and push the See All up so its jaws grab onto the dovetails of the base. Since the base I used has the crosspin slots for a Picatinny-type sight, I slid the See All until both locking screws were pushing down into the bottom of a slot, instead of on top of a locking ridge. I felt that would give a more secure attachment. But there were still some problems, as we shall see.

Sight-in
I sighted-in with H&N Baracuda Match pellets. They had tested well with the dot sight at 25 yards, and I felt they would be a good pellet for this test. But I had problems getting the pellet to go where I wanted. This is where I discovered that the See All sight behaves like a front sight and not like a rear sight. The sighting reticle must be moved in the direction opposite of where you want the pellet to go. The instructions included with the sight are very clear on this; of course, I wasn’t reading them — yet! There’s a marking on the right side of the sight that is supposed to tell you how to adjust the sight for windage, but I found it difficult to read.

I thought I’d solved the sighting problem and tried to shoot a first group, but the results were horrible. Pellets went everywhere! But within the first 5-inch, 10-shot group there were four holes together. Since I had seen the first hole through the spotting scope I knew the first 4 shots went to the same place, then the rest scattered everywhere. Pretty obvious what was wrong.

The sight was loose on the base! After tightening it down, I shot the first group for record. Ten Baracuda Match pellets went into 1.085 inches at 25 yards. It’s an okay group for open sights and an average spring rifle, but it’s horrible for a TX200.

See All sight Baracuda Match group 1
The first group of 10 Baracuda Match pellets isn’t much of a group for just 25 yards from a TX200. It measures 1.085 inches between centers. The sight was loose again!

Then, I checked the screws and found the sight had loosened, again, during the ten shots it took to fire the first group! Now I knew what to do. Check the screws after every shot and tighten if necessary.

Crosman Premier heavys
I switched to Crosman Premier heavy pellets for the second group, fully intending to come back to Baracuda Match pellets at the end of the test. But this shooting was proving tiring, and I didn’t want to jinx the other pellets by shooting them when I was tired. I checked the sight screws for tightness after each shot on this string.

Ten Premier heavys went into 0.978 inches at 25 yards. You can see a smaller group of 7 within the main group. It measures just 0.451 inches between centers. That tells me the See All Open Sight really works, but I was still getting used to it. The shots outside the main group are from my aiming errors, I believe.

See All sight Premier heavy  group
These 10 Premier heavys look a little better. The entire group is 0.978 inches between centers, but 7 of the pellets are bunched up pretty well in 0.451 inches!

I was learning to use the sight as things progressed. The space just above the reticle triangle is difficult to line up with a bullseye target — at least for me. But as things progressed, I discovered that I was aligning it faster and faster. I was learning to judge where the reticle was, even when I couldn’t see the tip. That’s no doubt what lead to those shots that are not inside the main group, and I think as I learn this sight more I will get better with it.

Crosman Premier lites
Next, I tried the 7.9-grain Crosman Premier lite pellet. By this time, I’d found it necessary to check the See All screws after only every 5 shots, and they were no longer loosening even then. Ten Premier lites went into a nice group that measures 0.686 inches between centers. It’s a very round group, which indicates I’m learning the sight picture as I go. But the Premier lite was also very accurate in the test using the red dot sight.

See All sight Premier lite group
Now we’re talking! Ten Premier lite pellets went into 0.686 inches, with 7 of them going into just 0.423 inches.

Baracuda Match
Now, it was time to return to the H&N Baracuda Match pellets and see what I could do. I was still checking the See All screws for tightness after every 5th shot, but they weren’t loosening. This time, I managed to put 10 pellets into 1.259 inches; but as you can see, 9 of them went into 0.695 inches. It’s clearly my fault the group is as large as it is. The See All Open Sight can make it much smaller, if used correctly.

See All sight Baracuda Match group 2
Ten H&N Baracuda Match pellets made this 1.295-inch group…which is horrible; but 9 pellets went into 0.695 inches, which isn’t too bad. Still, this pellet doesn’t compare with the Premier lites.

Conclusions so far
The See All sight does work as advertised. But you do need to read the instructions and follow them.

Small adjustments of the sight make very large changes in the impact point. Go very, very slow with your adjustments. And read the instructions to see which way to turn them. The markings for adjustment directions on the body of the sight are not very clear.

Plan on taking some time to get used to the sight. It does work, and I think it works well for people with poor eyesight; but it’s unlike anything you’ve ever used. Although it’s analogous to a dot sight, it works nothing like one in application.

I did find that I needed some light on the sight to see the reticle. I had the room lights on where I was shooting, which is something I never do with other open sights or scopes.

I think this sight may be better-suited to PCPs and CO2 guns than springers. But that’s just my impression from this first test. I’ll know more as the tests continue — which they will. I still think this sight is a significant new device.

My friend, Otho, is also testing a See All sight on some firearms for me. His eyesight is so bad that he hasn’t been able to use open sights for several years, so we’ll get a different perspective from him.

TX 200 Mark III new rifle
Brand new TX200 Mark III. It’s very similar to my TX; but the checkering is different, and the line of the forearm is more scalloped.

I didn’t plan on this test, but a big goof made during the last test of the red dot sight on the Air Arms TX200 Mark III forced me to rerun the test. The dot sight I used wasn’t anchored and was loose on the rifle at the end of the test. As long as I’m doing this again, I decided to make some lemonade. So, I’m going to show you a quick tip I use to anchor a scope or other optical sight when the mounts I choose have no stop pin built in. I may have covered this in the past, but bear with me as this is important to today’s test.

I want to get this test completed to clear the TX200 Mark III for the next test of the See All Open Sight. It turns out that the See All folks knew all about the problems their sight has with straight-line rifles like the M4, and they cover it in their FAQ section on their website. I didn’t read the FAQs before testing the sight; I just read the owner’s manual, so I missed that. But I thought you should know that they’re aware of the problem.

A quick fix to the scope stop situation
I often have to improvise things, and scope stops can give me problems. Since I have 25+ scopes on as many rifles, with a few extras sitting in the cabinet waiting to be mounted, I often run into a situation where the mounts that fit the scope I want to use (as well as the airgun I’m testing) don’t have the right stops. If the rifle has vertical scope stop holes like those on the TX200, the problem is solved by this quick tip.

The pictures show everything, but here’s what’s happening. A recoil pin is selected to fit in one of the rifle’s vertical scope stop holes. It doesn’t need to be attached to the scope mount — just dropped into the hole. Once it’s in the hole, slide the mount against it and tighten down the mount. As the rifle recoils, the mount tries to slide back, but that only jams it harder against the stop pin.

TX 200 Mark III quick scope stop pin
I used a real scope stop pin, but anything this size will work.

TX 200 Mark III quick scope stop pin in hole
Drop the pin into the vertical scope stop hole on top of the rifle. Yes, this is upside down on purpose. It fits the hole better that way.

TX 200 Mark III mount butted against scope stop pin

Slide the scope mount against the pin and tighten down the mounts. As the rifle recoils, it will just try to slide back and wedge against the pin tighter, so there will be no movement. The UTG Weaver-to-11mm adapter can be seen at the bottom of the mount. It’s the dark thing jammed against the pin.

Now that the fix is in place, we can begin the test. Since the red dot sight was off the rifle, I need to sight-in again. Hopefully, the sight will be pretty close this time! All shooting was from 25 yards with the rifle rested directly on a sandbag.

It took 3 shots to get on target this time. The sight was farther off than I expected.

Baracuda Match
The first pellet I tried was the H&N Baracuda Match. They did well in the last test when the sight wasn’t well anchored, so I figured they would continue to do well today. And they did. Ten shots went into 0.753 inches, and 9 of those went into 0.477 inches. That group is very round and uniform.

TX 200 Mark III Baracuda Match group
Ten in 0.753 inches and 9 in 0.477 inches. The H&N Baracuda Match pellets shot well using a dot sight.

JSB Exact RS
Next up were JSB Exact RS domes. At just 7.33 grains, they’re very light for a rifle having this much power. But they sometimes give surprising accuracy. Not in the TX200, however. The group was open and was the largest of the 4 pellets I tested. Ten RS pellets went into 1.071 inches at 25 yards.

TX 200 Mark III JSB Exact RS group
Ten in 1.071 inches at 25 yards. The JSB Exact RS dome is obviously not the right pellet for the TX200 Mark III.

Crosman Premier 7.9 grains
Then, I tried a group with the Crosman Premier lite. Ten went into 0.641 inches, with 9 making a 0.397-inch group. So, this light pellet that I didn’t know could shoot in the big TX turned in the second best group of the day — besting the Baracuda Match pellets!

TX 200 Mark III Premier lite group
Ten in 0.641 inches at 25 yards, and 9 in 0.397 inches. This is a great group!

Crosman Premier heavy
The last pellet I tried was the 10.5-grain Crosman Premier heavy. I expected them to beat the Premier lites, and that’s how it turned out. Though the group appears larger than the Premier lite group, it isn’t. Ten heavys went into 0.583 inches at 25 yards and this time there were no fliers. The group is elongated but has no one pellet apart from the group.

TX 200 Mark III Premier heavy group
Ten Premier heavys went into 0.583-inches at 25 yards, with no stragglers. This was the best group of the day!

Results
This test was conducted correctly, with the red dot sight anchored firmly to the rifle. I inspected the mounts after the shooting was finished, and the scope stop pin is still holding the rear scope mount firmly. These groups are representative of what I can do with a dot sight on a TX200. But how do they compare with the same rifle when it’s scoped?

With Baracuda Match pellets, the scoped rifle put 10 into 0.417 inches at 25 yards, while the same rifle and pellet made a 10-shot group measuring 0.753 inches with a dot sight. With Premier heavy pellets, the scoped rifle put 10 into 0.333 inches, while the same rifle and pellet made a 0.583-inch 10-shot group using a red dot sight. Clearly, the scoped rifle is more accurate than the same rifle with the red dot, although it’s still very accurate with the dot sight.

The question now is what will happen when I mount the See All Open Sight on this airgun? Can the groups be as small as those made by the red dot sight? Can they be smaller? We’ll find out next week.

TX 200 Mark III new rifle
Brand new TX200 Mark III. It’s very similar to my older TX, but the checkering is different and the line of the forearm is more scalloped.

Today, I’ll use the new Air Arms TX200 Mark III to test how a red dot sight works on a precision air rifle. This test was requested more than a year ago by blog reader Mannish in Mumbai.

Going into the test, I thought about the recent test of how high and low scope magnifications affect accuracy on the same air rifle. That test was suggested by blog reader duskwight from Moscow; and not only did I test the premise (in Part 11), he also tested it with a special guest blog. Both of us discovered that the magnification has no bearing on accuracy, and duskwight’s test was skewed toward favoring the lower-powered magnification!

I’m shooting the new TX200 Mark III with a Tasco Pro Point 30 red dot sight. The sight does not magnify the target at all; so, in essence, I’m shooting with open sights. I chose 25 yards indoors for the test, feeling that was enough range to show the trend. From the past testing of this rifle, I selected the H&N Baracuda Match pellet because I thought that it had demonstrated the best grouping at 25 yards. It was only after the test was completed that I discovered I’d selected the results of the other TX200 that’s my personal rifle. Oh, well! I do make mistakes from time to time.

Baracudas are still very accurate pellets in a TX200, and today’s test was not invalidated by their use. When you see the results I got, you’ll agree that this test is valid.

Dot sights in general
A dot sight is one that projects a red light in the center of the lens on the inside of the sight. No light leaves the sight, so this is not the same as a laser. Only the shooter sees the dot.

The dot is adjusted to shoot the pellet to the place you want it to go. The adjustments are the same as for a scope, but there’s no erector tube involved. Think of the dot as the intersection of the crosshairs. Canting the rifle is still possible and has the same affect. And, on a quality sight like this one, the brightness of the dot can be varied. That’s important because, as the dot grows brighter, it also appears to grow larger — covering more of the target. You want to cover as little of the target as possible, while still being able to clearly see the dot in the light you have. The Tasco Pro Point has a rheostat with 11 different brightness settings.

I adjusted the setting to No. 8, which gave me a dot I could see, yet was smaller than the black bull on the 10-meter pistol target I was using. I found that using the dot was the reverse of using a precision target aperture sight with an aperture front insert. There, you encircle the bull with the front aperture — with the dot you place the red dot inside the black bull, so the black encircles the red. Once I figured this out, I was satisfied that I could aim with precision.

Sight-in
The first shot was fired from 12 feet and landed at 6 o’clock, just below the bull. I was on paper, so it was safe to move back to 25 yards, where I fired a second shot. This one landed at about the same height as the first, but 2 inches to the right. I adjusted the sight up and to the left (the adjustments work just like the ones on a scope) and shot again. The third shot landed more to the left but was too high. The sight was adjusted again and the next shot nicked the 10-ring of the bull, so sight-in was completed.

I fired 9 more shots with this sight setting and never once looked through the spotting scope. The rifle was rested on a sandbag because we’ve learned the TX200 does very well that way. With each shot, I paid particular attention to centering the red dot inside the black bull. That was easy to do because I had the dot sized perfectly against the bull. But on shot 7, I noticed that the sandbag had moved forward by several inches, so the rifle wasn’t always resting at the same spot. I would correct that when I shot the second group.

When the group was finished I walked down to the trap to change targets. The first time I saw the group was when I entered my garage and saw one ragged hole! Holy cow! I did it! The dot sight is incredibly accurate!

TX 200 Mark III new rifle sight-in target and group
Here’s the first target. You can see how the pellets landed during the sight-in, plus you can see that first 10-shot group!

TX 200 Mark III new rifle first group
Ten H&N Baracuda Match pellets made this 0.619-inch group at 25 yards using a red dot sight.

While this group looks very good, it’s almost double the size of the 0.336-inch group I shot from my own rifle at 25 yards with this same pellet while using a scope. So, it does appear that using no magnification has opened the group just a little. The next group would tell for sure.

Back I went to 25 yards to fire a second group. This time, I paid attention to the exact spot that the rifle was rested on the bag, and I was also careful to center the dot every time. I really thought this group would be smaller than the first. When I walked down to see it, however, it was not only clearly larger — at 1.177 inches between centers — but it was also very horizontal. The first group had been vertical, if anything. I wondered what had happened.

TX 200 Mark III new rifle second group
Ten H&N Baracuda Match pellets made this very horizontal 1.177-inch group at 25 yards. This is clearly not as good as the first group, plus what’s with that flier on the right? There were no pulled shots in this string!

The first group had satisfied me that the dot sight was accurate. Perhaps I was losing concentration by the second group, which really wasn’t that many shots. Only 24 shots in all had been fired. And why had the rifle thrown a shot wide to the right like that? It was almost as if the sight was loose or something.

Oh, no!

That was when I remembered that I had done nothing about installing a vertical scope stop with this dot sight! I preach about scope mount slippage all the time to you readers, but apparently I can’t be bothered to do it right myself.

Sure enough, an examination of the mounts revealed they had slipped backwards on the rifle by 2 full inches! The Tasco mounts are 11mm; but being made for firearms, they have no provisions for a vertical scope stop, and so the inevitable had occurred. Naturally, I didn’t discover this until the range was completely knocked down and put away.

TX 200 Mark III new rifle mount slippage
All that work for nothing because I didn’t use a scope stop. The rear mount is only on the rifle by about a quarter inch! No amount of clamping pressure, alone, can hold a scope mount or this dot sight mount from moving, unless you’re using BKL mounts.

TX 200 Mark III new rifle mount slippage detail
This enlargement makes the rear mount easier to see. It’s almost off the rifle!

I don’t think this is so bad. After all, the rifle and sight turned in a good performance, even when the mount was not locked down. Imagine what it might do if it was solid.

What do I do?
There’s only one thing to do — rerun this test. I will install a vertical scope stop next time, and I’ll show you how easy that is to do. Then, I’ll shoot the same pellets at the same distance, and we’ll see exactly what a red dot sight can do. Since this was supposed to be the final test of the new TX200 Mark III, it seems I have a reprieve. I can’t argue with that!

TX 200 Mark III new rifleBrand new TX200 Mark III. It’s very similar to my TX; but the checkering is different, and the line of the forearm is more scalloped.

Today, we’ll look at the accuracy of the Air Arms TX200 Mark III at 50 yards. I can tell you that I learned a lot from this test. But that will all be summarized as we go. Let’s get started!

I shot the new TX directly off the same sandbag that was used at 25 yards. As you remember, I showed (after much coaxing from you readers!) that the TX shoots as well or better when rested directly on sandbags as it does with an artillery hold. The bag was crossways to the rifle, so the contact with the stock was minimized.

The day was perfect for the test. Not a breath of wind the entire time I was on the line!

The rifle is mounted with the AirForce 4-16X50 scope, which was selected so I could conduct another test for reader Duskwight after the regular test was completed. This scope is clear and sharp; and at 50 yards, I was able to bisect the small bullseyes with the reticle.

Sight-in
The rifle was still zeroed for 25 yards, so it had to be adjusted for 50 yards before anything else could happen. The first shot landed 3-1/4 inches low and 1-1/2 inches to the left. It then took another 2 shots before I was reasonable on the target. Then, I fired the first group with H&N Baracuda Match pellets. Ten landed in a group measuring 1.562 inches. It’s a fairly round group, but not as small as I would like from this rifle. So, I switched pellets.

TX 200 Mark III new rifle 50-yard target HN Baracuda Match
Ten H&N Baracuda Match pellets made this 1.562-inch group. It’s a bit large for a TX200.

JSB Exact Monsters
Next I tried some JSB Exact Monsters, which weigh 13.4 grains in .177 caliber. They went all over the place. When I went dowrange to retrieve the target, I saw that they were tumbling or yawing. They must be too heavy for the velocity the TX is able to generate.

Crosman Premier heavy
The third pellet I tried was the Crosman Premier heavy. I meant to bring Crosman Premier lites, but I grabbed the wrong box when loading up for the range. Fortunately, the heavy pellet was wonderful! Ten of them gave me a group that measured 0.658 inches between centers — or about as good as a top-flight PCP can do at the same distance! This is phenomenal accuracy for any air rifle at 50 yards!

TX 200 Mark III new rifle 50-yard target Crosman Premier heavy
Ten Crosman Premier heavies went into a tight 0.658-inch group at 50 yards. This one is a screamer!

First lesson learned
The new TX200 Mark III is every bit as accurate as my TX that’s well broken-in. No accuracy has been lost over the years, and the rifle can shoot this well right out of the box!

With lesson one under my belt, I adjusted the scope to lower the point of impact and moved to the next bull. The first shot landed where the last group was, then the pellets moved to the new sight adjustment.

Second lesson learned
Some scopes have stiction. After adjusting them, it’s best to shoot a couple shots to vibrate the reticle to its new location. I knew that, but made the mistake anyway. So, I’ve included the first shot, along with the group, to show you what it looks like. If this group had been as small as the one before, that first shot would really stand out. But I lost my concentration on this one and wasn’t holding the rifle as softly as I might have. This group of 10 measures 1.435 inches between centers, which isn’t that far from the first group of H&N Baracudas!

TX-200 Mark III new rifle 50 yard target Crosman Premier heavy group 2
The second group of Premier heavies opened to 1.435 inches. That’s more than double the size of the first group! Top hole to the left of the pellet was the first shot, which I disregarded, after the scope was adjusted.

Third lesson learned
While a rifle may be capable of shooting 10-shot 50-yard groups smaller than one inch, it may not do it every time! That small group may represent what the rifle is capable of, but not what it will always do.

Special test
Duskwight, our blog reader from Moscow, asked me to test the difference between a rifle shot with a low-power scope and the same rifle shot with a high-power scope. In other words, does magnification improve a rifle’s ability to group?

Well, common sense tells us that it does. Right? I mean, surely, if you’re able to parse the target to a finer degree, you must be able to group your shots closer together. Right? That’s what this test will determine.

That’s why I used a 4-16x scope on this rifle. I’d been shooting with 16x to this point, so now I dialed the power back to 4x and shot another group.

Wow! At 4x, the intersection of the crosshairs almost completely covers the small bullseye at 50 yards. As I shoot, I’m almost certain how this test is going to turn out. And it does. Ten shots on 4x with the same Premier heavy pellets landed in 2.208 inches. Looks like I was right about what low magnification would do.

The third group of Premier heavies — shot with the scope set to 4x — was 2.208 inches between centers at 50 yards. That’s quite a difference from the previous group, even though that group was already admittedly large.

But something nagged me about this group. I knew in my heart that I’d not given the rifle my best. I knew this group was going to be bigger than the last one while I was shooting it, so I was even sloppier with my hold.

It probably sounds like I need medication to suppress my dual personalities while at the range, but I assure you I’m not talking to myself — at least not loud enough for others to hear. What I’m doing is a little soul searching while I’m still out at the range and have the time to do something about it.

I adjusted the scope back to 16x and shot another 50-yard group. This time, I did everything the way I should have. The hold was completely relaxed. I fully expected to be rewarded with another of those sub-inch groups, but that didn’t happen. This time, I shot a 10-shot group measuring 1.935 inches between centers. Oh, well! I was probably tiring out from all the concentration.

TX-200 Mark III new rifle 50 yard target Crosman Premier heavy group 4
Ten shots at 50 yards with the scope set to 16x netted this 1.935-inch group.

Fourth lesson learned
Sometimes, you just can’t will the results to happen the way you would like. I put my whole heart into this group, and this is what I got. Maybe that’s what it feels like to be 66, dried-out and ready for the old-folks home!

Fifth lesson learned
I called that first great group of Premiers a screamer. Now you see why that is.

Nevertheless, I owed it to Duskwight to try the rifle on low scope magnification one more time, and this time to do my very best. So I did. This time, 10 pellets went into a group that measures 1.481 inches between centers. That’s right, it’s SMALLER than the group shot on 16 power! I noticed that the bull was just visible behind the crosshairs; and if I really tried, I could hold on the target in exactly the same way every time. Apparently, I did, because this group fired on 4x is smaller than the previous group that was fired on 16x.

Ten shots at 50 yards with the scope set to 4x made this 1.481-inch group.

Sixth lesson learned
Although it isn’t conclusive, it looks like you can shoot just as accurately on low scope magnification as you can on high magnification if you take the time to do things right.

Seventh lesson learned
Looking at both groups fired on 16x and both groups fired on 4x, it sure looks like the point of impact never changed! Some of you have asked about that in the past. The design of the scope determines whether the impact point will move when the scope’s power is changed, but these days a lot of variable scopes stay right where they were when the power’s adjusted.

Eighth lesson learned
Of the five groups fired with Premier heavy pellets on this day, only one is smaller than one inch. And it’s significantly smaller! When you see those great groups in the future, you must ask yourselves what the rest of the groups look like.

Ninth lesson learned
I may be old and dried-out, but I can still shoot — a little. I get tired as the shot count increases, so that needs to be factored in to my tests from now on.

Summary
I’m very pleased with what this new TX200 Mark III has done so far. I think the rumors that the TX quality may have slipped are just that — rumors! Individual guns may have problems; but overall, the TX200 is one fine air rifle. Next, I plan on mounting a red dot sight and testing it for accuracy, again, to see what the differences are.

Crosman MTR77NP air rifle

Today, I’m testing the Crosman MTR77NP scoped air rifle for accuracy at 25 yards. This is going to be a very different accuracy report, for I have no targets to show you. Well, there is one target, but it wasn’t shot with the test rifle.

What gives?
In the last report, I mentioned that I wanted to mount a different scope on the test rifle and test it at 25 yards. I thought the Bug Buster 3-9x scope would be a good one, and I also shimmed under the rear ring because the rifle was shooting low in the 10-meter test.

I thought the rifle would group about 3 times larger at 25 yards than it had at 10 meters, but I also hoped some pellets might remain tighter than that. What happened, however, was just the reverse. Instead of 3-inch groups I got 5- to 6-inch “patterns.” I won’t call them groups because not all pellets fired even hit the target trap. And when that happens, I stop shooting that particular pellet immediately.

Crosman Premier lites
First up was the pellet I thought had the best chance to do well — the 7.9-grain Crosman Premier. They had done well at 10 meters with just 2 pellets outside the main group. Had they held to my 3X size increase, they would have grouped into about 2.2 inches; but when the third shot landed 6 inches away from shots 1 and 2, and then shot 4 landed 5 inches from that pellet, I stopped shooting.

I checked the scope mount to see that it was still tight. It was, and I’m pretty sure this scope is a good one because it has done well in other tests on other airguns. So, Premier lites are out.

H&N Baracuda Match
Next, I tried some H&N Baracuda Match pellets. But they were no better. They hit the target lower than the Premiers, and 3 shots landed in about a 5-inch pattern. Then, one pellet missed the target trap altogether. I stopped shooting after that shot, but I wasn’t done with this pellet.

I got the Air Venturi Pellet Pen and Seater and deep-seated a couple Premier lites to see what affect that would have. The point of impact changed, but the accuracy didn’t improve. And when the third shot missed the trap, I stopped shooting Baracudas.

RWS Hobby
The next pellet I tried was the RWS Hobby, which gave such a nice, round group at 10 meters. Two shots landed together, and I thought we were on the right road; then the next shot hit about 6 inches away from them. The 4th shot missed the trap altogether, and I stopped shooting that pellet.

RWS Superdome
By now, I was in a quandary. Was it me or the gun or the scope? I went back to 12 feet from the target and confirmed that the scope was still shooting to the same point, then I went back to 25 yards and tried an RWS Superdome. I had confirmed at 12 feet that the Superdome would be on paper at 25 yards and the first shot was. It landed high, but in good enough position to keep shooting. The next shot missed the paper altogether and I don’t know where it went. That was it for Superdomes.

What to do?
By this point I was really shaken. My confidence was ebbing fast and I needed to end this session on a high note. So I grabbed my Beeman R8 Tyrolean and a tin of Air Arms Falcon pellets and shot a final group of 10 at 25 yards. This one turned out good, as I expected it would. That’s where today’s target comes from. It isn’t the best group I’ve shot with the R8, but it’s a darn sight better than I did with the MTR77NP. Ten shots went into 0.41 inches.

I shot this 10-shot group of Air Arms Falcons with my Beeman R8 Tyrolean, just to confirm that I still knew how to shoot. It measures 0.41 inches between the 2 centers farthest apart.

What’s next?
I need some time to think about why this rifle might be performing like it is. If one of you made a report like this to me, I would tell you to check the scope because that sure seems like what it is. But I did check the scope and found no problems. The one thing left to do is to crank the elevation down all the way and all the way to the left and shoot a group. If it tightens up, then it was the scope. If not, it’s either the mounts or the rifle.

A little tip
What I did with the R8 today is a handy tip to remember. Sometimes the problem is you — or you wonder if it might be. Shooting a good group with a rifle of known accuracy is the best way to rule that out.

TX 200 Mark III new rifle
Brand new TX200 Mark III. It’s very similar to my older TX, but the checkering is different and the line of the forearm is more scalloped.

I’m writing this extensive report to fully explore the fabulous Air Arms TX200 Mark III, which is without a doubt one of the finest spring-piston air rifles in the world! The good news is that it’s still available today. The better news is that it’s everything it’s cracked up to be! Writers have a few trite phrases to convey quality in the airgun world. “As good as a TX 200″ is one of them, and it’s very high praise.

There are 9 links above that will take you all the way back to the beginning, when I started by testing my own well-broken-in TX 200. But now I’ve shifted over to a brand-new rifle that Pyramyd Air sent to me to test. Some readers wondered if my rifle, which is so well-used that it might be performing above the bar, so to speak, because of the use it’s had. They wanted to see a rifle that’s being made today, and also one without all the wear on the parts. That’s what we’re testing now — a brand-new TX whose only shots are the ones you have witnessed on this blog.

Scope
The TX has no sights and must be either scoped or have some other kind of optical sight mounted. One of the tests we’re going to do with this rifle is to mount a red dot on it and see what that does for it. Blog reader Mannish from Mumbai asked for that test a long time back.

We’re also going to test the effects of shooting the gun at 4X and again at 16X with the same scope. Reader Duskwight asked for that — to see if the increased magnification would affect the group size. I also want to see if changing the magnification changes the point of impact, so that test will be a twofer.

I’m leading up to the scope I chose for this test. I might have selected the same Hawke 4.5-14X42 Tactical Sidewinder that was on my TX when I tested it, but that didn’t give me all the magnification I wanted for Duskwight’s test. So, I selected a vintage AirForce 4-16X50 scope, instead. Mine is older than the model being sold today, but the specifications are essentially the same. For a mount, I selected a nondescript 1-piece mount. I chose it because it has a vertical scope stop pin for the TX scope stop holes, plus it has the height needed for the scope’s objective bell to clear the spring tube. I have no idea who made it.

The test
I started sighting-in at 12 feet, putting 3 pellets into the target and adjusting until they were in line with the center of the bull, more or less. They were high, so I cranked down about 4 complete turns on the elevation knob, knowing that back at 25 yards the gun would be shooting higher than at 12 feet.

When I shot the first pellet at 25 yards, it was still about 1.5 inches high, so a couple more turns down on the elevation knob brought it to the center of the bull. As always, I tried to intentionally keep the pellets from striking the center of the bull, as that erases my aim point very quickly. The sight-in was now complete with about 7 shots being expended.

All of today’s shooting is at 25 yards, which is really close for a TX. I rested the rifle directly on my sandbag, with the bag turned sideways, so the rested area touched about 5 inches of the forearm. I used an ultra-light hold, and the groups showed the results. I selected a couple pellets that had done well in the test of my personal TX and one that had never been tested for accuracy before.

H&N Baracuda Match
The first pellet was the one I used to sight-in the rifle — the H&N Baracuda Match. It was landing to the left of the aim point and in the center of the bull for elevation. Ten shots landed in a group that measures 0.417 inches between the centers of the 2 pellets farthest apart. That’s well within the range fired by my personal TX at 25 yards.

Ten H&N Baracuda Match pellets went into 0.417 inches at 25 yards. The rifle was rested directly on the bag.

JSB Exact RS
Next, I tried a pellet I haven’t tried for accuracy in the TX — at least not that I can remember. The JSB Exact RS dome is a very lightweight pellet for a rifle this powerful. The first shot landed about 1.5 inches above the spot where the Baracudas were hitting, but it was still on paper, so I continued to shoot. Each shot that followed seemed to drop a bit lower on the paper, and as I was shooting I discovered something important. The rifle shoots this pellet very well, but it is extremely hold-sensitive. Moving the rifle a quarter-inch on the sandbag makes a tremendous difference. So, I was able to adjust the hold carefully and get the pellets to land closer together.

I think the RS pellet can be made to shoot, but it isn’t worth the effort when there are other pellets that shoot even better without all the fuss. The 10-shot group I got measures 1.501 inches between centers, which is terrible; but 6 of those pellets were the ones I took special pains to hold exactly the same, and they measure just 0.496 inches between centers. That’s the potential of this pellet when you handle the gun like it’s a soap bubble!

Ten JSB Exact RS pellets went into 1.501 inches at 25 yards, but 6 of them are in 0.496 inches. It’s too much trouble to shoot that carefully, if you ask me, but the rifle can do it.

Crosman Premier heavy
The last pellet I tested was the Crosman Premier heavy. The group was a phenomenal 0.333 inches between centers! That’s slightly better than the best group I shot with my own TX at 25 yards, but the difference is only 3 one-thousandths of an inch and could easily be hidden by an error in measurement. So, the 2 rifles are equivalent.

TX 200 Mark III new rifle Crosman Premier heavy 25-yard group
Ten Crosman Premier heavys made this 0.333-inch group at 25 yards. Clearly, the new TX 200 Mark III is a tackdriver!

I could have shot other pellets and shown you more targets, but by now you’re getting the picture. The new TX is the same as it has always been — one of the finest and most accurate air rifles on the market.

Next
Next, I’ll test this rifle at 50 yards. I’ll do essentially the same test that I did with my own TX at that distance, but then I’ll add the 4-16X test. That will tell us if there’s an advantage to more magnification, and it will also show if the point of impact changes as the magnification changes.

After that test, I plan on mounting a red dot sight on this rifle and testing it at 25 and 50 yards. I think that will end the test of this rifle, unless something else comes up.
