Today I check the velocity of the Chrosman Challenger youth 10-meter target rifle. In 2009, the last time I tested the rifle, I adjusted it to get lots of shots with H&N Finale Match High Speed pellets. They were 7-grain wadcutter pellets that are no longer available. Back then they averaged 545 f.p.s. for 116 shots on a fill. We will see where they are today — 11 years later. read more

I’m doing this accuracy test because I discovered that in a test run many years ago I shot my best targets when holding the Haenel 311 target rifle with an artillery hold. In the last test I laid the rifle directly on the sandbag and I wondered how the artillery hold would affect the groups.

The test

I shot 5-shot groups with each pellet, but with one pellet I shot several groups for different reasons. I did try my hardest to shoot well. I shot from 10 meters.

Air Arms Falcon

First up was the Air Arms Falcon pellet — the only domed pellet in the test. In the last test with the rifle resting on the sandbag, the 311 put 5 Falcons into a 0.466-inch group. This time using the artillery hold the same Falcon pellet went into 0.571-inches. It’s close, but the bag rest seems better. read more

Today we look at the accuracy of the MAR177 for the first time. But before we do — a saga!

Sighting in the MAR

I wanted to shoot the rifle with the iron sights it came with first. To me putting a scope on a military rifle is a bit redneck, unless that rifle is a sniper rifle. 

I shot from 12 feet and the pellet hit the target 2 inches below the aim point. I knew it would climb when I backed up to 10 meters, but it only climbed a quarter inch. Oh, no — I have to adjust the front sight of an AR for elevation. No military person who has carried the M16 likes to adjust its front sight for elevation. It is a slow and tedious process of pressing down a spring loaded pin and turning the front post one click at a time until its where you want it. The rifle was shooting low so I started adjusting the post down. After three clicks the post bottomed out, as in no more adjustment. read more

The importance of dry-firing

by B.B. Pelletier

Today’s report was requested by blog reader NotRocketSurgery. He’s been watching the NSSF videos on You Tube about shooting in the Olympics, and the subject of dry-firing comes up repeatedly. He wanted to know why. I’ll address this subject with enthusiasm, because this is something with which I actually have some experience.

Have you ever watched the Olympics and seen a slalom racer standing at the top of the course with his or her eyes closed, swaying as they envision running the course? We might have made fun of such behavior in the 1960s, but today we know that’s what all the winners do. They’re conditioning their minds to respond correctly to the course ahead of them.

Dry-firing a gun is like that, but it’s more than a century older. We don’t close our eyes, nor do we sway about, so onlookers don’t have quite as much to comment on. When we shoot our guns without discharging a shot (dry-firing), we’re conditioning our brains and many muscles to work together.

I don’t suppose there’s a machine the downhill skiers can get on to simulate the experience of skiing while standing still, but all world-class target air rifles and air pistols do have a dry-fire mechanism built in. To not have one automatically eliminates the gun from serious consideration.

Top target shooters spend much more time dry-firing their airguns than they do shooting pellets. How much more differs from shooter to shooter, but I’ve heard one Olympic air pistol shooter say the number is five times as much. So, for every shot that makes a hole in paper, the shooter has also fired five more shots without discharging the gun. And it’s very common for a world-class shooter to shoot a full match every day, which would be 60 shots for a man or 40 for a woman. And five times that much dry-firing.

How do you dry-fire a gun?
You don’t just pick up the airgun and start shooting. Practice in the dry-fire mode must be identical to shooting a match, though a target doesn’t have to be in a bullet trap or even the correct distance from the shooter, since it’s all a simulation. I am going to describe this from an air pistol shooter’s perspective, but what I say applies equally to air rifle shooters. The moves are just different.

For those who are interested, I wrote an extensive blog on the subject of shooting a 10-meter target pistol. Part 3 demonstrates raising the pistol and sighting. You do it this way with both live-fire and dry-fire.

When you dry-fire, you first go through all the motions of raising the pistol and settling on the target. That is not a random movement! The gun is held on the shooting table in front of the shooter in a certain and repeatable way, and is raised to the same height each time. Some shooters like to raise the sights above the bull and then settle back down until the sights are aligned with it. Others like to raise the gun until the sights come in line with the bull on the way up and go no higher. Each shooter has a preference; but whatever it is, they always do it the same way.

Once the sights are on target, the shooter has up to about five seconds to get the shot off. Much longer and the gun will start to wander more than a little, so timing is very important. An amateur might hold out for the perfect sight picture for twice as long as a world-class shooter, but you’ll see the top shooters lower their guns if they don’t get the shot off within the time limit.

Many shooters, including me, take up the slack of the trigger’s first-stage pull as the gun is settling into position. To someone who is not trained, this sounds dangerous, and it actually is — because their guns will go off at a time that is not entirely of their choosing. But a top competitor knows exactly where the trigger releases, and they can wait until the sights are perfectly aligned before applying the final few grams of pressure that cause the sear to release.

When the sear releases, the shooter continues to aim at the target, noting where the sights are. With some practice they learn to call their shots — which means they know exactly where each pellet went without seeing the hole it made in the target. This is something you can read about and never understand. As you train, it comes to you all at once. And when that happens, you never forget it. You’ll be able to call your shots from that point on.

After the shooter has called the shot (to himself), the gun is lowered to the shooting table, reloaded and the cycle begins again. There are 90 seconds for every shot in a formal match. It sounds like a rush, but it’s actually more than enough time for a well-trained shooter. You don’t lower the gun without taking a shot more than a handful of times in a match, if that much, so time is never your enemy unless you have an equipment problem. I never thought about the time remaining in a match. What I concentrated on was how many pellets remained in my pellet tray, because that told me where I was in the match.

The dry-fire mechanism
I told you that all world-class airguns have a dry-fire mechanism, but now I’ll tell you that some are better than others. Most of them have some sort of switch that is set one way for live fire and another way for dry fire. The guns that have that usually have a very realistic trigger-pull in the dry-fire mode.

I shoot a SAM M10 that was made through cooperation between Anschütz and Caesare Morini. I’ve never shot a full formal match with it; but back in the late 1990s, I did shoot it for the record several times. That was when I was shooting at my peak, so I noticed things more acutely than I do today. I found the trigger to be very nice, though by that time I’d tested enough FWBs, Steyrs and Walthers to know what a world-class trigger should feel like. The M10 has a good trigger, but it’s not as nice as an FWB P34 trigger, which was the last FWB target pistol I tested.

The dry-fire mechanism on the SAM 10 is a lever on the right side of the action. Pull is straight back and the trigger is cocked, but the hammer isn’t. When you pull the trigger, it releases the sear without releasing the hammer to strike the firing valve — hence the dry-fire. Those who own a gun with double-set triggers know the feeling of the set trigger breaking is not the same as the feeling of the gun actually firing. With an airgun, which doesn’t recoil or make a lot of noise when it fires, this feeling is much more noticeable.

On the SAM 10 target pistol, the dry-fire lever at the top of the receiver is pulled back each time to cock the trigger. You can feel the sear release when the trigger is pulled; but since the hammer was not cocked, it doesn’t strike the valve and no air is exhausted. read more

FWB 300S vintage target air rifle: Part 5

by B.B. Pelletier

Part 1
Part 2
Part 3
Part 4

The FWB 300S is considered the gold standard of vintage target air rifles.

This is a test I said I would do the next time I got a calm wind day at the range. That day came last Friday, and I took the opportunity to test the FWB 300S at 50 yards with a scope. This test was designed to see if there is any discernible accuracy difference between pellets that are sorted by weight and those selected at random from the tin. If you read part 4, you’ll see that I was surprised to find that these JSB Exact RS pellets I selected for their accuracy had such a variation in weight. I sorted through almost 40 pellets to find 20 that weighed exactly 7.3 grains. Though the weight difference was only four tenths of a grain, it was more than expected and more pellets were affected than I thought.

The JSB Exact RS pellet was chosen because of previous performance demonstrated in part 3. And I had to choose a domed pellet because out at 50 yards no wadcutter can possibly be accurate — I’ve proven that on many occasions in the past.

In part 4, I tested the rifle at 50 yards using the target sights that come on it, and I got two groups of 10 shots each. One was with random pellets taken from the tin. That group measured 1.689 inches between the centers of the two widest shots, while the other was 10 weight-sorted pellets that grouped in 1.363 inches. I didn’t feel that test was conclusive, so I wanted to return with the rifle scoped to see what it could do.

Not only did I mount a scope on the rifle, I also installed a scope level, and on every shot the bubble was leveled. That eliminated the possibility of any cant, so the rifle was always shooting in the same orientation.

The scope hangs over three-quarters of the loading port, making loading a chore. Notice how close together the scope rings are, yet they occupy the entire length of the dovetails. The 300S is not made for a scope! Notice, also, the scope level that was consulted on every shot.

I mounted a Leapers 3-9×50 scope with AO. It’s an older version of the one I linked to, but the specs are mostly the same. Notice in the photo that this scope was almost too long for the rifle, even though it was mounted at the extreme rear of the spring tube.

Where I had used a 3-inch bull target with the aperture target sights, I switched to the smaller 10-meter target when using the scope. The pellets were falling off the target paper anyway and onto the plain backer paper attached to the target frame, because of the large drop of this pellet at 150 feet.

Perfect day
I couldn’t have asked for a better day in which to shoot. Since I was at the range very early, there was absolutely no breeze. The sun hadn’t risen very high, so I didn’t need to shield my non-sighting eye. The rifle rested in the bunny bag dead calm, so altogether this was as perfect a test as I could have run.

Bore already seasoned
Because the bore had been shooting JSB Exact RS pellets last, it was already seasoned for this test. Still, I did shoot the rifle a few times to wake up the action. Then, I began the first group of unsorted pellets.

This time, the pellets did very poorly — grouping 10 shots into 3.152 inches at 50 yards. The group is very elongated, looking like a large velocity swing. The group measures just 1.178 inches wide, which is less than half the height.

Ten unsorted JSB Exact RS pellets strung out vertically at 50 yards. The rifle shot much better with target sights! Should I have warmed the gun more?

Next, I shot the pellets that were sorted by weight. Ten went into a group measuring 1.606 inches across. This group is fairly round and well-distributed, so it makes me wonder all the more about the first group. Perhaps the gun needed longer to warm up for the first group than I allowed?

This group of 10 weight-sorted RS pellets is much rounder, but it’s no better than the best group shot with target sights. read more

Okay, on to today’s report.

I didn’t think this day would come so soon, but I’m going to show you what happens when you shoot the FWB 300S at 50 yards. Or more correctly…when I shoot it! I say that because 50 yards is a distance at which all false pretense of accuracy falls away. Fifty yards is a harsh challenge for a 650 f.p.s. air rifle like the 300S. All the wonder of those tiny groups at 10 meters becomes doubt that you can even shoot this far when the range stretches out more than four times as far.

I needed a windless day and as luck would have it, I got one. Or at least one where what little breeze there was could easily be managed. When I got set up to shoot, it was about 8:15 a.m., and the breeze was running from still to an occasional puff of about 1 m.p.h.

I used the sandbag rather than the rifle rest because I already knew the 300S did well on it. I first fired about four rounds to warm the action and to “awaken” the mechanical parts. I’ll talk a lot more about that in a PCP primer I’m writing, but even spring-piston guns have to wake up if they’ve sat for more than a couple hours.

I’m shooting the JSB Exact RS pellet for this test. We all agreed that to test the gun with wadcutters at this range would be unfair, because wadcutters are known to be inaccurate after about 25 yards. And the RS pellets proved to be the most accurate domed pellets in the accuracy test I did.

For targets, I wanted to use the 50-foot timed and rapid-fire pistol targets that I always use at 50 yards. The bull measures just larger than 3 inches, which is a good size for most peep sights at 50 yards. I like these targets also because they measure 10.5″x12″, which gives a lot of room for the pellets to miss the mark and still be seen. I knew the pellets would drop when going 50 yards, and I’d planned to stack two targets — one above the other, so I could aim at the top bull and possibly hit somewhere on the target below. But I only had two of these targets! I’d failed to pack enough of the right kind of targets in the range box. Though I had plenty of targets, only two were what I wanted.

No problem, I thought. Years ago, I figured if this ever happened I would use 10-meter pistol targets instead of these larger targets. They’re on smaller paper, but I could still place one above each larger target to use as an aim point. Ten-meter pistol targets have a bull that measures 2.35 inches across. It looks similar to the larger bulls when you look at them casually, but at 50 yards the difference through the sights is noticeable. They’re too small in the front aperture, which leads to possible aiming errors. I could see that on the first group I fired and also when I examined the group afterwards.

The first target suffered from an aim point that was too small for precision. It measures 2.407 inches between the centers of the two holes farthest apart.

As I predicted, the group dropped about eight inches at 50 yards, so the group was printed on the target below the one I aimed at. I knew that the smaller bull was too small to work well at this distance. But there was another way of doing this.

I still had two of the 50-foot timed and rapid-fire targets stapled to the target backer; and underneath everything, I’d stapled a 2’x4′ sheet of plain target paper. It’s the back of a silhouette target that I always use when I’m unsure of where my bullets or pellets will go. The plain light paper allows me to see the holes even though they don’t strike the intended target. Because it’s so large, it covers the entire target backer; so, unless the rifle is really out of whack, I’ll see where the pellets are going.

Then, I proceeded to shoot another 10-shot group of unsorted pellets at the larger bull on the left, knowing that they would strike the plain target paper below this target. They landed about two inches below the target and gave me a perfect group of 10 on the plain paper.

This time, the bull was filling the front aperture as it should, so the group was much better. It measures 1.689 inches between centers. Remember, this is a 10-shot group. It’s about 40 percent larger than a 5-shot group fired under similar conditions. That doesn’t mean that it’s exactly 40 percent larger; and, yes, it’s possible for the first 5 shots to land the farthest apart, so that a 10-shot group doesn’t grow any larger. But the probability that you’ll do that is very low. If you keep on shooting after 5 shots, it’s more likely that your group will continue to enlarge until it’s, perhaps, 40 percent larger after 10 shots than it was after the first 5.

Ten-shot group at 50 yards with unsorted pellets. Ten shots made a 1.689-inch group. Nine of the shots went into 1.015 inches. The larger aim point helped reduce the group size.

Some notes on sorting the pellets
I had sorted the JSB pellets the evening before going to the range. Because JSB pellets are so accurate, I thought they’d also be very uniform, but they weren’t. To get 20 pellets that all weighed 7.30 grains, I had to sort through almost 40 pellets! The weight ranged from 7.10 grains to 7.40 grains. While that isn’t as large a spread as other pellets, it was still a surprise. I thought I might find two or three pellets that didn’t weigh the same, but it was worse than that.

By this time it was around 9 o’clock, and the breeze was picking up. I had to wait for breezes of 3 m.p.h. to die before shooting. When they did die, though, the air was perfectly still again. This time, 10 pellets that were sorted by weight grouped in 1.383 inches. That isn’t much better than the unsorted pellets, and it was not the result I’d expected.

Ten-shot group of weight-sorted pellets at 50 yards made this 1.383-inch group. Not much improvement over the unsorted pellets! You can see a very small 5-shot group at the left of the larger group. That group measures 0.577 inches between centers, but I can’t say that it indicates anything. read more

Part 1
Part 2

The FWB 300S is considered the gold standard of vintage target air rifles.

We’ll look at accuracy today, but this isn’t our last look at the 300S. You convinced me to take this rifle to the range and test it at 50 yards. I’ll do that, but I have to have a perfectly calm day for it. Kevin also convinced me to test weight-sorted pellets against pellets straight from the tin, so that’s how I’ll do the test. I want to use domed pellets at that distance, so today I’ll be looking for a good one that the rifle likes.

More 300S trivia
Mac sent a batch of photos to show some details that few people have ever seen. I’ll show a couple today and more in the next report.

Remember the Running Target rifle we talked about last time? Well Mac sent photos to show how the loading port differs from the one found on the standard 300S match rifle. The port is the same size, but FWB has rotated it to the right to make access for loading a little easier. I guess they expected a lot of right-handed RT shooters, or more likely they also built one in a left-hand version. Mac’s is the right-hand rifle.

The standard 300S loading port is centered on top of the spring tube, to be equally accessible from either side.

On the right-hand Running Target rifle, the loading port is rotated to the right for better access from that side.

All of today’s shooting was done from a rest at 10 meters. I attached the Gehmann color filter wheel to the rear aperture and used the yellow filter to sharpen the bulls. It seemed to work okay. Unless I were to use it for a lot longer, I really could not say that it adds anything. I don’t shoot a 10-meter rifle often enough to notice things like that.

Pellet head size is important when shooting a target rifle, and I shot pellets with heads of 4.50mm and 4.52mm, but none with a 4.51mm. Interestingly, the 4.50mm heads ranged from bad to good; so even when you have a single head size, you aren’t done looking for the right pellet.

Pellets that didn’t make the grade
I tried nine pellets in this test. Seven were wadcutters and two were domes. RWS Hobby pellets and Gamo Match were the two that didn’t cut it. Both shot so poorly that I didn’t waste any time with them. Oddly, in the test of the FWB 150 I did last year, RWS Hobbys were tied with H&N Finale Match Pistol pellets as the best ones. Go figure!

I shot two 5-shot groups each with the other 7 pellets. And with 6 of the 7 pellets, the second group was smaller than the first. That lends support to the notion that an airgun barrel needs to be seasoned before it will perform its best.

Honorable mention
The following pellets did okay, and I would have continued to use them if I had nothing better. Each of them seemed to want to do better than they were doing, but I tried an extended test with one of them and it didn’t pan out.

The RWS R10 Match Pistol pellet came the closest to making the final cut. Maybe if I shot it more it might improve. But the best group of five I got measured 0.153 inches between centers.

I tried the Vogel match pellet that Scott Pilkington makes here in the U.S. It’s a great match pellet, but for some reason the 300S didn’t care for it that much. This is the pellet I shot four groups with, but the best of them measured 0.192 inches between centers. No dice!

JSB S100 Match pellets were another tease. The best group measured 0.113 inches between centers, but in the end it just wasn’t enough to make the cut. This was the only pellet I tried that had a head size of 4.52mm. All the others were 4.50mm. This pellet did very well in an Edge match rifle from AirForce, so I thought it might have a chance here, but no dice.

The one domed pellet that I thought might work but didn’t was the Air Arms Falcon pellet. The best group out of two was 0.167 inches between centers. It was a nice, round group; and because this isn’t a wadcutter, the group looks about half the size it really is. With domes, you have to make extra allowances for the skirt that tears through the target paper.

The winners
Three pellets showed great promise in the 300S, and one of them was superb. The JSB Exact RS was the best domed pellet, putting 5 shots into a beautiful round group that measured just 0.111 inches between centers. Because these groups are all so small, I’ve enlarged the photos for you to see them better. My dime is in the photo for reference. This is the pellet I will take out to 50 yards.

JSB Exact RS pellets made a nice small, round group. They will be shot at 50 yards in this gun.

I tried both H&N Finale Match Pistol pellets and H&N Finale Match Rifle pellets in the 300S, and both turned in a wonderful performance. These are the pellets the gun likes best. The Finale Match Pistol pellets turned in a group that measured 0.117 inches between centers. It looked very good when I saw it, but one that’s even better was yet to come.

That’s a nice tight group of five H&N Finale Match Pistol pellets. It measures 0.117 inches between centers. read more
