Posts Tagged ‘Crosman Premier light pellets’

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.
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.
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.
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 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.

Today, we’ll look at the first of 2 accuracy tests planned for the Crosman MTR77NP scoped air rifle. As you know, this rifle has no open sights; so, the first thing I did was mount the Centerpoint 4X32 scope that’s included with the gun. That went quick because the scope caps have 2 screws each, but there was no slippage of the scope in the rings during this test.
The scope is very bright as you would expect a 4X scope to be, but at the 10-meter distance I shot in this test, it was fuzzy. The parallax is fixed for a further distance that isn’t indicated on the scope. I can tell from examination that it’s set farther than 25 yards.
I’m testing at 10 meters today and will take the best pellets into the next test, which will be at 25 yards. The first pellet up was the 7.9-grain Crosman Premier. You will remember from the velocity test that the test rifle shoots considerably slower than its advertised velocity of 1,000 f.p.s. with lead pellets. It went an average of 866 f.p.s. with 7-grain RWS Hobbys.
I discovered that the rifle is shooting low, even with the scope adjusted up high. For the next test, I’ll shim the rear scope ring. That should raise the pellet up far enough.
Crosman Premier lites
At 10 meters, 10 Premier lite pellets made a group that measures 0.721 inches between centers. The group has a main group of 8 pellets within it and 2 flyers, though there were no shots that were pulled. This is a case where a better scope might do better on target because the image was so fuzzy that I might have been off the aim point by 1/8 inch at times.
The MTR77NP fires with a solid thump. There’s no vibration, and the shot cycle is very quick. The recoil through the butt isn’t sharp the way it is on many gas-spring air rifles. And the A2 stock seems to be ideal for handling the recoil of this rifle without stinging your cheek.
Now that I’ve shot the gun for accuracy, I can tell you the trigger-pull is very long in stage 2. The pull length of stage 2 is supposed to be adjustable, but I turned in the screw about 7 full turns and nothing changed. It feels like a placebo screw; or if it does adjust anything, the effect is very small.
H&N Baracuda Match
The next pellet I tested was the heavy H&N Baracuda Match. This pellet showed some promise in the velocity test, and I thought it might do well in this rifle. Ten of them went into a group that measured 0.982 inches between centers. Like the Premier lite, there were flyers outside the main group, though I did not see them when shooting. I’m beginning to think that the next test needs to be conducted with a different scope.
The scope mounts had loosened by this point in the test. The rings remained tight, but the screws that attach the rings to the base on the rifle loosened up. I tightened them and also checked them after every 5 shots from this point on.
Next, I tried 10 RWS Hobby pellets. They went much lower and also to the left. They actually missed the target paper. The group was round and measured 0.826 inches between centers.
Crosman SSP Hollowpoint
I did check the Crosman SSP hollowpoint that was the lead-free pellet I tested in the velocity test, but after 2 pellets missed the target backer altogether, I stopped shooting. Not the pellet for this rifle.
JSB Exact Express
The last pellet I tested was the 7.87-grain JSB Exact Express dome. I haven’t had much luck with this pellet in the past, but I keep trying it just in case. Alas, the MTR77NP doesn’t like it, either. Ten pellets went into a vertical 1.661 inches at 10 meters. Another pellet to not use in this rifle.
Evaluation so far
I like the way the rifle feels when it fires. It has good power and a solid thump when it fires. The trigger-pull is long but not too creepy.
The scope leaves a lot to be desired. I think I’ll replace it with a Bug Buster 3-9X scope for the next test, and I’ll shim the rear scope ring before mounting it on the rifle. That should give the rifle the best chance to do well at 25 yards.
Obviously, the pellets to try are the Crosman Premier lite, the H&N Baracuda and the RWS Hobby. The Hobbys will be at their maximum recommended distance, but they may surprise us.
If you like black rifles and have been considering the MTR77NP, I think it’s worth a look. We’ll know better after the next test.

This report is getting long and perhaps a little confusing, so let me explain what I’m doing. We’ve been looking at the Air Arms TX200 Mark III underlever air rifle. I used my own TX for the first 6 parts of the report. In Part 7, I introduced a brand new TX that Pyramyd Air sent for me to test. Many of you were concerned that the rifle had changed somehow over the years since mine was made, and perhaps what’s shipped today isn’t the same rifle…so I agreed to test a new one for you. The first look at that rifle came in Part 7 of the report, and in Part 8 we looked at the velocity.
Today ,I’m going to show you the trigger in detail, describe how to adjust it and explain why I always say the TX trigger is an upgrade of the Rekord trigger that Weihrauch introduced back in the 1950s. To get to the trigger adjustments, the triggerguard must be removed. But today I’m going farther into the gun to show you the entire trigger assembly. That will help me explain how the trigger functions.
The stock needs to come off to get into the rifle, so I did that first. Just remove 2 forearm screws and 2 more triggerguard screws.
Once out of the stock, the action and trigger can be seen clearly.
Here you see the disassembly bolt (all the way to the lef). Turn it out, and the rifle comes apart. You can also see the 3 trigger adjustment screws. On the trigger blade are screws to adjust the first-stage length and adjust the sear contact area. Behind the trigger blade is an Allen screw that adjusts the trigger pull weight. Behind that is the threaded hole the rear triggerguard screw goes into.
If I were just adjusting the trigger I wouldn’t need to go even this far. Just remove the triggerguard and start by adjusting the trigger return spring tension. I found that was all I needed to do on the test rifle, as the first-stage length and sear contact area were right as they came from the factory. But you can adjust either of them or both.
To take the trigger unit out of the gun, I removed the disassembly bolt. As it turned, I pressed down on the entire barrelled action with the end cap resting on a soft cloth pad. When the bolt was free, the mainspring decompressed less than 2 inches.
When the trigger unit comes out of the rifle, it’s still pinned to the end cap and spring guide like this. Now, the trigger unit looks familiar to Rekord owners because the 2 pins that hold it to the end cap are visible.
Because I want to show you how this trigger works, I’m going to continue to disassemble the end cap. The 2 pins that hold the trigger unit in the cap are driven out. They are several times harder to remove than Weihrauch trigger pins. This unit is together very tight!
Once the trigger assembly is out, we can see how it differs from the Rekord.
The trigger assembly is similar to the Rekord — but also different. The box is riveted together instead of being a folded sheet metal structure. There’s an additional pin, forward of the trigger blade, and internally there are bearings where the Rekord parts just turn on pins.
So far, I’ve shown you the differences but not described how they work. For starters, the Air Arms trigger has adjustments for the first-stage pull and for the sear contact area, as well as for trigger-pull weight. The Rekord has the sear engagement adjustment and the pull weight adjustment but not the first-stage adjustment. But that isn’t what makes the Air Arms trigger better.
What makes the Air Arms trigger better is the presence of bearings instead of just pins. The parts are also more finely fitted, which has to be done during manufacture because there’s no money in the gun for costly hand-fitting. And the trigger isn’t the only place that’s different. The piston is also different.
The TX200 has what I will call a circular piston. All pistons are circular, of course, but most of them are held from rotating by the cocking shoe. Because of that, the piston can have a hook that’s engaged by the trigger when the gun’s cocked. That’s how the Weihrauch rifles that use the Rekord trigger are made. But what if the piston was free to rotate on its axis?
Blog reader RidgeRunner asked how the TX piston was cocked by the sliding compression chamber. The answer is that the chamber pushes the piston back until the trigger catches it. The piston rod is so long that it can be caught by the trigger while the piston is still inside the compression chamber.
When the gun is cocked, the piston rod comes back and pushes the trigger parts into lockup. As they lock up, a hook catches the rear of the piston rod and holds it until the sear releases it.
The ability of the piston to turn on its long axis while being supported front and rear by bearings adds smoothness to the powerplant without sacrificing power. A centrally located air transfer port that’s centered on the piston boosts the air scavenging efficiency and therefore the available power. The TX200 Mark III is giving all the power it can from a powerplant that’s still smooth and easily cocked.
How is the trigger after adjustment?
Before I adjusted the trigger, it released crisply at 1 lb., 12 oz., which is 28 oz. All I adjusted was the trigger return spring tension and now the trigger breaks cleanly at 12 ounces. So the adjustment dropped one entire pound. And, yet, the sear still has the same contact area, so it’s just as safe as before.
A good tuner can adjust a Rekord just as light, but the sear contact area won’t be as great as it is at 3 lbs. The Air Arms trigger allows for this adjustment without sacrificing any safety. That’s what I meant by the TX trigger being more finely adjustable that a Rekord.
By the way, the work done here, including taking the pictures, took a total of 30 minutes.

This is the second look at the brand-new TX200 Mark III that Pyramyd Air sent to me for this test. We’ve been looking at my older TX200 Mark III until recently, but now we’re looking at the gun that comes when you order it today. Over 40,000 TX200 air rifles have been sold since the model was first introduced in the late 1980s, and today’s version is probably the best of all.
Today’s look will be a traditional Part 2 velocity check because that’s one of the things you readers have been asking about for many years. I keep telling you that the rifle comes out of the box shooting slower than it’s rated; but as it breaks in, the velocity continues to climb. Today, we get to really look at the gun right out of the box. I’ve purposely held off shooting the rifle more than just a few shots, so this test can be as accurate as possible. Here it goes.
The TX200 Mark III is rated to shoot 930 f.p.s. in the .177 caliber we’re testing. That’s not an advertiser’s claim. That’s based on my testing the guns over the past 20 years. And it’s also not with lead-free, lightweight pellets. It’s with Crosman Premier 7.9-grain lites. In other words, 930 f.p.s. or more is what you can expect from your TX200 with Premier lites, as long as it remains original. But it doesn’t start out that fast. It’s been my experience with TX200s that they start out shooting Premier lites around 875-890 f.p.s. I’ve written these words before doing any testing of today’s gun, so I’m going to find out what actually happens right along with you.
Crosman Premier lites
Well, shut my mouth! Imagine my surprise when the first Premier lite came out of this new rifle at 936 f.p.s.! Boy, was I off the mark on this one!
The first 10 Crosman Premier lites averaged 926 f.p.s. The spread was broad for a TX — from a low of 917 to a high of 936 f.p.s. That’s 19 f.p.s. difference across 10 shots. And there was a smell of burning oil in the room, so I know combustion had something to do with both the higher velocity and the larger spread. At the average velocity this pellet produces 15.05 foot-pounds of muzzle energy.
H&N Baracuda Match
Next, I tried H&N Baracuda Match pellets. They weigh 10.65 grains, making them a heavy pellet in .177 caliber. They averaged 830 f.p.s. in the test rifle, with a spread from 821 to 835 f.p.s. At the average velocity, this pellet produces an average 16.30 foot-pounds of energy at the muzzle. That’s uncharacteristic of a spring rifle — when a heavier pellet produces more power than a lighter one. But that’s what this rifle did.
Whenever airgun manufacturers wanted to show how fast their guns were in the days before lightweight lead-free pellets, they invariably tested them with RWS Hobbys. At just 7 grains, this wadcutter is one of the lightest lead pellets around and should give the highest practical velocity the rifle is capable of.
Hobbys averaged 1011 f.p.s., with a low of 1000 and a high of 1022 f.p.s. Right there you have proof that Air Arms is being very conservative in their velocity estimates. At the average velocity, Hobbys produced 15.89 foot-pounds of energy at the muzzle.
This TX is shooting much faster than I anticipated. It’s doing essentially its advertised velocity right out of the box — with Crosman Premier lites! What will happen as it breaks in? My thinking is that it will continue to get faster like the other rifles I’ve seen, but this one may not get that much faster. It may be closer right now to where it will end up after 10,000 shots have gone through it. My well-broken-in TX now averages 963 f.p.s. with Crosman Premier lites. It started out around 875 out of the box. I think this one will eventually be just as fast, but not proportionally faster.
I mentioned some noise when cocking the rifle in the first report. That has already begun to decrease with just the few shots in this test. I think it may disappear entirely in a few hundred more shots.
The cocking effort is at 34 lbs. right now, but I can feel some stiffness in the linkage. I think that’s going to smooth out and drop by several pounds over time.
Of course, the TX trigger is extremely adjustable, so this is just a measurement of how it came from the box. In the next installment, I’ll discuss adjusting the trigger in great detail.
The trigger breaks crisply at 1 lb., 12 oz. as it’s currently set. That’s 28 oz. It feels heavier than the trigger on my TX, which it should, since mine is releasing at just 9 oz., or roughly one-third the weight of this one. The point is that when it comes to triggers, TX200s are so refined that almost no other sporting spring airgun has a trigger in the same category.
Observations thus far
So far, the new TX is performing pretty much as expected, with the exception of shooting way faster than anticipated. Everything else is right on the money, so I know the elves at Air Arms are still making these airgun the same old way — which is very good.
I have a couple of other experiments planned for the TX after the final accuracy test, and I was going to go back to my own rifle after I tested this one for accuracy; maybe I should do them all with this one. One test was requested by blog reader Mannish from Mumbai, who asked me how dot sights do on springers. I had planned on testing that on a TX, so perhaps I might use this one. Blog reader duskwight wondered if the group size will change when switching your scope from 4x to 16x. I’d planned on testing that at 50 yards with a TX; and with that particular test, we’ll get a bonus — seeing if the point of impact changes as the power changes. Good stuff!
But the trigger adjustment is next.
by Tom Gaylord, a.k.a. B.B. Pelletier
This is my second trip to the rifle range to shoot the TX200 Mark III at 50 yards. Last time, I shot only heavy pellets; today, I’ll shoot the hopefully more-accurate lightweight pellets, plus one JSB medium-weight pellet that several blog readers have had success with.
I also shot the rifle laying across the sandbag, instead of in the long groove down the center. Several readers said that was the best way to rest the rifle directly on the bag.
The day was perfect for shooting pellet guns at long range. There wasn’t a breath of air during the entire session.
The first pellet I tested was the Crosman Premier lite — a 7.9-grain dome that some say is the most accurate pellet of all in the TX200. The group landed about 2-1/2 inches above the aim point because the rifle was still sighted for heavy pellets. But it was centered perfectly, and 10 pellets made a group measuring 1.077 inches between centers. That’s not a bad group, but I’ve seen TX200s do better at 50 yards.
That was a good start. The group was only slightly larger than the smallest group fired in the session before, which was 1.042 inches.
Following the first group, I adjusted the scope down several clicks. I wanted to keep the shots on or near the bull at which I was aiming.
JSB Exact 8.4-grain dome
Next up was the JSB Exact 8.4-grain dome, a pellet that several readers said was the most accurate one in their TX200s. Alas, that wasn’t the case in my rifle. When the first 5 pellets landed in a very vertical 2.40 inches, I stopped shooting. There’s no way the last 5 shots can improve things. Clearly, this isn’t the pellet for my rifle!
JSB Exact RS
The next pellet I tried was one I had high hopes for — the 7.3-grain JSB Exact RS dome. It does so well in so many spring rifles; but, once again, the TX200 Mark III is not one of them. Ten pellets made a group that measured 1.957 inches. It’s a vertical group, as well.
Air Arms Falcon
About this time I was suspecting that the rifle does not like lightweight JSB domes. The next pellet up was the Air Arms Falcon, another lightweight domed pellet that’s also made by JSB. While Falcons are great in many air rifles, the first 5 landed in an open group measuring 1.658 inches, and I stopped right there. It looked like this pellet wasn’t for my TX, either.
What was happening?
Three out of 4 pellets I brought to the test were not good. Had I made a mistake with the Premier lites, as well? Was that good first group just a random event? I decided to shoot another one to see. This time, though, I laid the rifle the long way in the bag to see if there was any discernible difference.
Ten pellets went into a group measuring 1.241 inches this time. That is much closer to the first group than any of the other 3 pellets tried on this day, though it’s still larger. Maybe, laying the rifle lengthways made the difference? I don’t think so.
I decided to shoot another group with the rifle laid lengthways, again, just for comparison. This time I hit the jackpot and all 10 pellets went into 0.658-inches.
The TX 200 Mark III is capable of phenomenal accuracy at 50 yards, even when rested on a sandbag. From the limited testing I did I can’t say laying it crossways or lengthways is better. It works well both ways.
My rifle seems to shoot best with 7.9-grain Crosman Premier lite pellets. It does not seem to like any light pellets made by JSB.
This is not the end of our testing. Pyramyd Air has sent me a new TX200 Mark III that I promised you I would test right out of the box. Some of you have been concerned that my rifle is too well broken-in, and you think it may not reflect what you will get if you buy one. So, we shall see!
As a final note, I’d like to point out that I got several groups that were okay with the Premier lites and one group that’s exceptional. That’s the way it goes with any airgun — I don’t care which one you’re talking about. All the talk about half-inch groups at 50 yards has to be taken with this firmly in mind. You’re going to shoot larger groups most of the time.
That being said, Premier lites seem to be the most accurate and also the most forgiving pellet we’ve tested in my TX200. They may not always shoot into a super-tight group, but they’ll always shoot where you want them to. That’s what’s important.

Wow! More than one month has passed since the last part of this report. I’ve been to the Roanoke airgun show and also out to the rifle range at least 3 times trying to get the data for today’s report, but what a quest it has been! It all boiled down to false confidence in my ability to get the job done. I’m used to certain rifles cooperating with me every step of the way, and this time I got called by the fates who expose pride for what it is.
I’m not going to bore you with all the details, but I will point out the most recent example of my stupidity because it’s a lesson for us all. When I went to the range last week, I thought I was ready to complete my 50-yard test of the .25-caliber Benjamin Marauder. I’d swapped the scope mounts from a previous test because they were too high. The new mounts were lower, and I didn’t have to hold my head as high on the comb. I knew this would help with the accuracy. But then I went to the Roanoke airgun show, and forgot that I’d made this change.
What’s most important about the change, though, are that the new mounts were vintage B-Square adjustable mounts. And the rear ring was jacked up higher than the front. I always liked that setup because it gets the drooper problem taken care of on the first shot — even if there isn’t one! But not if you forget that you did it!
And that’s why this report didn’t happen last week. I had the Marauder at the range with the TX200 Mark III, on which I reported last weekWhen I shot the Marauder, there wasn’t a pellet hole on the paper. And I’m not just talking about the target paper, either. I mean the 2-foot x 4-foot backer paper that I use whenever I have a rifle that’s not known to be sighted-in.
Naturally, I was disappointed. This was a Marauder after all, and I expected it to go right to the point of aim. After shooting just two 8-round magazines, I took the rifle off the line and put it away. I needed to look into the situation deeper and figure out what was wrong.
What was wrong, was that I had forgotten about the new scope mounts. When I looked at the scope back in my office, I immediately saw that the rear was higher than the front. Then I vaguely remembered something about changing the mounts before going to the Roanoke airgun show, so I reread the last report and discovered what had happened. The gun had not been sighted-in with the new mounts. It was obvious that the scope was set up for a rifle with severe barrel droop, and this rifle doesn’t have that.
I even went back to the rifle range last Friday and looked at the backer board where my target and backer paper had been stapled. Sure enough, above where the top of the paper had been there was a hole in the backer board. It had the appearance of a nice rifle group. And some of the holes in the group appeared to be .25 caliber.
Suspecting what happened, I started shooting at an aim point much lower than my anticipated target. Sure enough, my pellet was hitting the paper about 16 inches high and 6 inches to the left. That’s a problem I can deal with! All I had to do was adjust the scope down and to the right, and I was on target. It took me less than 10 minutes to get my groups landing where I wanted at 50 yards. Now, it was time to test the rifle.
The first group was shot with H&N Baracuda pellets. In the past, these were the most accurate .25-caliber pellets on the market, but they have since been replaced by several others, including one huge surprise that emerged in this test! The group measured 1.021 inches between centers. It’s a good group for any rifle at 50 yards, but I did think the Marauder might be capable of better.
I should mention that I was firing two magazines of eight shots each in this test. So the groups that you see have 8 pellets and not 10 in them. I recharged the rifle with air after every 16 shots because the reservoir pressure had dropped to around 2,100 psi by that point. That was as low as I felt it could go and still be accurate.
JSB Exact King
The next pellet I tried was the JSB Exact King, a .25-caliber pellet that’s shown a lot of promise in recent testing. The first group I shot measured 1.447 inches between centers. That’s not very good for a PCP rifle at 50 yards. Interestingly, however, 7 of those 8 shots went onto 0.719 inches, and that is good. I hoped that the one flyer was an anomaly, and that a retest of the same pellet would do better.
The second group of JSP Exact Kings when into 1.094 inches. That’s a lot better, but it still wasn’t what I’d hoped for, so I left the Kings to try other pellets.
Another stunning pellet in .25 caliber is the Benjamin dome. It has no model name, but you could think of it as a Premier pellet because it looks similar to the other pellets in the Premier line. The first group of 8 pellets measured 1.226 inches between centers, which was again larger than I was looking for.
The second group of Benjamin domes measures 1.06 inches. While that’s better, I still thought the rifle could do more.
The last pellet I tried was the .25 caliber Predator Polymag. It showed well in the 25-yard test and earned its place in this test. There really aren’t a lot of options when it comes to accurate .25-caliber pellets, and I think we’ve included all of them in this test. Yes, there are other brands out there, but do they perform? In my experience, they don’t.
The Predator is a hollowpoint pellet that has a red plastic tip in the center of the nose. Normally, hollowpoints fall off in accuracy at around 25 yards, but this pellet doesn’t. That tip seems to do its job.
The first group of Predators measures 1.121 inches between centers. Once again, that’s okay for 50 yards, but it’s nothing to scream about. But the second group measures 0.808 inches between centers. That’s what I was looking for! While the Marauder can’t be expected to shoot that well every time, this group proves that it has the potential. And it does it with a pellet that is acknowledged to be a great hunting pellet!
No .25-caliber airgun has ever been as accurate as the best .22 or .177 guns. What we see from this test is a range of results that represents what the .25-caliber Benjamin Marauder can do at 50 yards. I think these groups show what this gun can do very well. Sure, if you shoot more there will be some smaller groups. But there will also be many more groups that are larger than those shown here. I think we can safely say the Marauder in .25 caliber is capable of putting 8 shots into one inch at 50 yards when you do your part.
The .25-caliber rifle uses a lot of air! I was getting just 16 good shots in this test on a 3,000 psi fill. Compare that to the 32 good shots I got in the test of the .177-caliber rifle filled to the same pressure.
From a handling standpoint, there isn’t a nickel’s worth of difference between the .177- and .25-caliber rifles. The trigger can be adjusted to operate virtually the same, and the stocks feel the same. The one small difference is the .25-caliber gun does move back slightly with each shot. I didn’t feel that with the .177, but I definitely felt it in this test.
If you want a .25-caliber hunting air rifle, I think the Marauder is a good candidate for your short list. It’s powerful, accurate, quiet and reliable. How much more can you ask?

Today’s lesson is about sighting-in a rifle scope. I know that scope mounting and sighting-in seems daunting, but it isn’t as hard as you might imagine. In the last report, I sighted-in at 10 feet. Because I got lucky, it took just 2 shots to sight-in the rifle; and when I finished, I told you I was ready to try the rifle at 25 yards. I said, based on the results of my 10-foot sight-in, it should be on paper at that distance (actually it would be on target at any distance between 20-35 yards, given the TX 200′s velocity), but it probably wouldn’t be exactly where I wanted it. Today, we’ll find out if that prediction is correct.
Let’s get to it
So, I set up the bench and started shooting at 25 yards. I chose H&N Baracuda Match pellets because they were the pellets I used at 10 feet. If you forget what happened during the 10-foot sight-in, you really should read that report first to appreciate what’s happened here. A quick summary would be that I guesstimated how high above the bore the center of the scope is, and shot at a dot the same distance above the desired point of impact. Aiming at the upper dot, I was trying to get the pellet as close as possible to the dot beneath, which meant the scope would be shooting to exactly the point of aim (offset by the scope and barrel centers) when all trajectory was removed from the equation.
The two dots are separated by approximately the same distance as the center of the barrel and the center of the scope. Aim at the top dot and hit the bottom dot. This is the first shot. After I adjusted the scope, the second shot went through the bottom dot.
Shooting at 25 yards
The first shot at 25 yards landed slightly above and to the left of the bullseye. I then shot 4 more that moved over to the right just a little. I took the center of the larger 4-shot group as the place where the scope was really sighted, and I adjusted from there. In all it took me far less than 10 minutes to sight-in this scope, even though I spread the reports over a period of 2 weeks.
The first 5 shots at 25 yards landed high and to the left, with the very first shot landing farthest to the left. I took the center of the main group of 4 to be the point of impact. From there, I adjusted the scope down and to the right.
Bear in mind that I do not want to hit the dot at the exact center of the bullseye, if possible. That’s my aim point; and if I destroy it, I have to guess where to hold the crosshairs.
Now that the rifle is sighted-in, I shot the first 10-shot group at 25 yards with the stock rested on my open palm, next to the triggerguard. I got a fairly good 9-shot group, but I managed to throw one shot to the left. Nine went into 0.376 inches, but that one stray shot opened the group to 0.605 inches. I was moving around too much in the artillery hold, and I could see it through the scope.
Stability seemed to be my problem, so I slid my off hand out to where I could feel the cocking slot on my palm. The rifle seemed to rest steadier, but the group doesn’t reflect that. Ten pellets went into 0.714 inches, which is horrible for a TX200. Obviously, this wasn’t the right hold for the rifle. And just as obviously — I was having a bad day.
Sometimes, a disaster (okay, maybe just a small setback) contains the seeds of discovery! Since I couldn’t hold the rifle steady enough to shoot a good group on this day, could I rest it directly on the sandbag and do better? We’ve been interested in the fact that some spring guns don’t seem to need the artillery hold. I already told you the TX200 is one of them. Perhaps, this was the day to find out.
For the next group, I rested the rifle in the long vee-groove in the top of my sandbag. The bag is so long that the rifle rests there without needing a rear bag for support. It was dead-steady when I sighted this time.
The results tell the story! This time, all the shots went to the same place. The group is very round and tight, at 0.336 inches. This is clear proof that the TX200 can be bag-rested when shot, and also that the rifle is incredibly accurate. I’ve shot even better groups with it in the past; but whenever I do things right, I always get good groups with this rifle.
Notice that in today’s test only a single type of pellet was used. That kept things simple and allowed me to look at other things without worrying about which pellet to choose.
So, we’ve learned 2 things. The first is that it’s easy to mount a scope on an air rifle and to sight it in. It doesn’t take a lot of time, nor do you need any fancy equipment. Of course, if your rifle has a drooping barrel problem there will be more to do, but these are the basics.
Second, we’ve learned that the TX200 can shoot as well or better when rested directly on a sandbag as it can with an artillery hold. That’s certainly true if you’re shaking when holding the gun.
Tomorrow is the 50-yard test, followed by a full test of a brand-new TX200 Mark III, I hope. There are some other things that can be explored with this rifle as our testbed. All in all, we have a lot of things left to do with this air rifle!
