My rifle is actually a BSA Super Meteor.
Today, you’ll see how I fixed the bad muzzle crown on the BSA Super Meteor, and then we’ll see if that had any effect on the rifle’s accuracy. You might want to read Part 7, again, just to remind yourself of what I faced.
The BSA project has been just that — a project from the start. All I wanted to do was test another vintage spring-piston air rifle for you and report the results, but this particular air rifle has challenged me at every turn. From the time I bought it at the Roanoke airgun show last September, it’s been nothing but a prolonged learning scenario. I won’t bore you by recapping all that’s happened; but if you want to find out, read Parts 1 through 7.
At the end of Part 7, I showed you a nasty muzzle crown, which I surmised was the reason that all the pellets were leaving the barrel with a yaw to their axis. They weren’t tumbling, because every one of them struck the target paper in exactly the same orientation. They were yawing, or traveling forward while pointing off to one side. Because the barrel is rifled, they were spinning on their long axis, but that axis didn’t happen to coincide with their flight path.
The BSA Meteor crown has some serious nicks in it. The dark spot at 10 o’clock is the deepest. Compressed air could escape through this channel before any other part of the pellet leaves the bore, and the jet of air could push the pellet over on its side.
The solution was to crown the bore; but as you can see in the picture, the Meteor’s muzzle is counterbored by more than an inch. In other words, it isn’t where it appears to be from the side. It’s deep inside the barrel, where the theory says it shouldn’t get damaged as easily. Only this one was — perhaps from over-zealous cleaning through the muzzle. Who knows? The point is that it had to be fixed.
My shooting buddy Otho suggested a piloted counterbore to face off the crown true and square to the axis of the bore. And he volunteered to make the pilot, so I slugged the bore for him and found it was a diameter of 0.176 inches. That seemed odd to him because it’s larger than the bore of a .17-caliber rimfire bullet that’s about 0.172-inches. But that’s the difference between .17 caliber and .177 caliber — which is important for airgunners and firearms shooters to know. The pilot he made measures 0.1745 inches and fits the Meteor’s muzzle comfortably.
Otho made the pilot for this counterbore.
The counterbore chucked up perfectly in my portable electric drill. I allowed extra length for the bore to go down into the barrel and touch the muzzle without the drill chuck touching the barrel.
The counterbore is chucked in the drill and set to run true. It sticks out far enough to cut the crown without the drill chuck touching the barrel.
Plugging the barrel
Before starting the work, I pushed 3 fat pellets into the breech and then pushed them with a cleaning rod to within 2 inches of the true muzzle. These will keep the metal chips from dropping down the bore.
I oiled the counterbore and pilot with a good grade of light machine oil before inserting it into the muzzle of the gun. The drill was set on a slow speed, but I can also control the speed by how hard I squeeze the trigger. I wanted a slow steady turn without putting much pressure on the drill. The counterbore is sharp enough to cut the soft barrel metal without a lot of encouragement.
The drill is set to run slow, and I’m also slowing it more with the trigger. You don’t need speed for a cut like this.
After about 10 seconds of cutting, I removed the counterbore and cleaned the new crown with a cotton swab. There was a band of bright metal around the muzzle where the counterbore had cut. Upon close examination, I could still see gouges in the bright band. The gouges were deeper than the first cut.
The new crown is bright after the first cut, but there are still gouges that need to come out.
I cleaned the counterbore with a swab and oiled it again. Then, I made a second cut on the crown. This time, I felt the drill pulse as the cutter removed the uneven metal. It became smooth, and I knew the cut was finished. When I cleaned and inspected the new crown this time, it appeared smooth and even. The job was done.
I apologize for the blurriness of this picture. Focusing on the crown is very difficult when I’m also trying to light it from the same axis as the lens is pointing. The lens is about one inch from the end of the barrel, and this was the best picture I got. There are still some faint marks on the crown. After examination with a loupe, I didn’t think they would be a problem.
At this point, I felt the crown was as clean as I could get it. And there was a simple way to see if this had made a difference. I drove the pellets in the bore out the muzzle and a few steel chips came with them. Next, I shot two RWS Hobby pellets offhand from 12 feet. If the crown was good, they would cut the paper perfectly instead of hitting sideways. And that’s what happened.
So, I backed up to 8 yards and shot 2 more shots from an improvised rest. These 2 pellets landed very close to each other and also showed no signs of tipping. I felt the job was done.
The two lower shots were from 12 feet. They confirmed the pellets were hitting the paper straight-on. The two upper shots were from an improvised rest at about 8 yards. They told me the crown is probably working.
Now for the test!
The test is a rerun of the Part 7 accuracy test. I used every pellet from the last accuracy test and shot at the same 10 meters.
Ten Eley Wasps went into 2.256 inches at 10 meters.
If you compare these targets to those in Part 7, one thing jumps out at you. None of these pellets tipped when they went through the paper. So, crowning seems to have solved that problem!
But the accuracy seems no better. The Hobbys did group better in this test, but the Falcons grouped worse. With groups this large at 10 meters, I’m not willing to say anything has improved. I’ve had cheap Chinese air rifles group better than this.
I have one trick left up my sleeve. I’ve noticed that the Meteor rear sight seems hinky and difficult to adjust, and I suspect it jumps around as I shoot. It’s not loose to the touch, but I don’t trust it to hold zero.
I’ll do one more test of this rifle with either a dot sight or with the See All Open Sight if I can get it mounted to the Meteor. If that doesn’t work, I’ll probably abandon this air rifle as a bad investment.

Falke model 70 is a quality breakbarrel spring-piston rifle from the 1950s.
Today is accuracy day for our Falke model 70 breakbarrel. I tested this one at the same time I tested the BSA Meteor Mark IV; and after that horrible test, I was praying that this rifle wouldn’t let me down. When I bought the rifle at last year’s Roanoke airgun show, the seller told me it shot pretty well. I was hoping to see that — especially after what happened with the Meteor! It did okay in the velocity test, so there was no reason to suspect it wouldn’t also be accurate.
The Falke did not disappoint, though it’s important to bear in mind that this is a vintage spring rifle made by a company that went out of business a half century ago and not some tackdriver made by a target gun manufacturer. When you shoot one of these air rifles, think in terms of a vintage Diana model 27 rather than a Walther model 55.
The Falke has open sights, so I like to start testing guns like them at 10 meters. They’re usually right on target; but if they’re off, 10 meters is close enough that they won’t be off that much. Open sights seldom have the same kind of problems as optical sights.
The Falke is a vintage airgun, so I felt it deserved a vintage pellet — at least for starters. The first pellet I tried was the Eley Wasp. Of course, I also tried Wasps with the Meteor and look where that got me! But the Falke was far more forgiving. In .177 caliber, the Wasp pellet is medium-sized — nothing like the oversized 5.56mm (.22 caliber) Wasps pellets we use in guns that have large bores. Wasps fit the Falke 70 breech well, but they weren’t tight. They didn’t fall out, but they also didn’t need to be pushed into the rifling. They went in easily.
When I saw the group, I was amazed! Eight of the ten Wasps were in a tight group that measures 0.276 inches between centers. The 2 pellets that aren’t in the main group open it to a much larger 0.862 inches, but I’m thinking those 2 shots might have been due to small sighting variations.
Eight of ten Eley Wasps went into a tight 0.276 inches, but the final 2 opened it to 0.862 inches.
The rifle has a comfortable feel when shooting. I’d called it a single-stage trigger, but it’s actually 2-stage. Stage 2 is very subtle and takes some time to get used to it to feel it every time, but it breaks cleanly enough for good work. The post-and-bead front sight is somewhat difficult to use precisely; but at 10 meters against a black bull (with a 6 o’clock hold), it’s good enough.
I like the way the breech locks when it closes. The spring-loaded lock breech jumps into position. After it does, you cannot feel any movement in the breech.
After the Wasps, I adjusted the rear sight higher to get into the bull. Then, I started a group with RWS Hobby pellets; but after just 3 shots had gone into 1.371 inches, I gave up. No sense finishing a group like that! Hobbys are often a very accurate pellet in vintage airguns of the same power as this Falke model 70; so it was worth a try, but when things go that wrong that fast it’s time to move on.
Crosman Premier lites
Next, I tried the 7.9-grain Crosman Premier lite pellet. This is another pellet that often does well in lower-powered spring guns like the Falke 70. But not this time! Ten went into a group that measures 1.164 inches between centers. You might wonder why I was so quick to abandon Hobbys yet stuck with Premier lites to the end. Well, this group just kept growing larger with each shot. It wasn’t until close to the end that I saw how large it was going to be.
Air Arms Falcons
Next, I tried some Air Arms Falcon pellets. The Falcon is a 7.33-grain domed pellet made for Air Arms by JSB on dies that Air Arms owns, so it’s unlike anything else JSB makes. It’s too simple to say the Falcon is just a JSB Exact RS under another label; for although both pellets weigh exactly the same and are both domed pellets, they don’t perform the same. Often Falcons will shoot well when Exact RS pellets won’t.
In the Falke 70, they did pretty good! Of course, I didn’t miss the irony of shooting a falcon pellet in a falcon rifle!
For starters, they went to the exact center of the bull. I know this thrills some folks who need to see the pellets impact there; but like I always say, I’m looking for the smallest groups — then, I’ll adjust the sights later. But when luck happens and I get this result, I can’t deny that it thrills me a little. Ten pellets went into 0.762 inches, which is okay but not great. But within the main group there are 7 pellets that made a much smaller group measuring 0.387 inches. Like the Wasps, I cannot help wondering if I could do better.
H&N Baracuda Match
The last pellet I tried was the H&N Baracuda Match. While this seems like an overly heavy pellet for such a low-powered spring rifle, I’ve found they often do quite well in some guns. They were certainly worth a try. Although the rear sight was adjusted up for most of the other pellets, the Baracudas hit low on the target. But they did put 8 of 10 into 0.44 inches, which is very good. And, again, there are 2 pellets that didn’t want to go into the main group. They opened the group to 0.742 inches, making this pellet the most accurate of those tested.
Should I test at 25 yards?
The Falke model 70 will never have a scope. I sense the accuracy potential of the rifle exceeds the precision of the sights. Two and perhaps even 3 of these groups should have been one small hole, but for sighting errors. I am tempted to back up to 25 yards and have a go. We shall see.

My rifle is actually a BSA Super Meteor.
I’m headed to Las Vegas this weekend for the 2014 SHOT Show, so I’m asking veteran readers to help the newer readers more than usual. And I thank you in advance.
Tuesday’s blog will have something very important. It’s the first day of the SHOT Show, and I’ll show you something brand-new. It’s a pretty big deal, so it’s worth a look. Now, let’s get to today’s report.
Today, we’ll look at the accuracy of the BSA Super Meteor Mark IV that I’ve been working to restore. This report was never supposed to be an ongoing saga. It was supposed to be a quick 3-part look at a vintage air rifle, but the Meteor that I bought at the Roanoke airgun show last September turned out to need almost one of everything. So, I hunkered down and went to work.
I said in one of the earlier parts that fixing up an old spring-piston rifle is a lot like rebuilding an old tractor. Man, was that ever a prophesy! I had no idea that I would have to get down into the guts of the rifle to get it shooting again; but if you’ve followed along on all the earlier parts, you know that’s exactly what happened. Now that the old girl is shooting like she should, let’s see how accurate she is.
This is a vintage spring rifle with open sights, so I like to begin shooting those at 10 meters. Since I have no idea how accurate or inaccurate they are, it’s best to start close. If the groups show some promise, I can always back up to 25 yards and shoot a second test.
I figured a vintage airgun deserves a vintage pellet, so I broke out some obsolete Eley Wasps in .177 caliber as the first pellet. The first 2 shots were to sight in, and shot #1 was low, so I tried to adjust the rear sight up using the adjustment wheel. Alas — it didn’t move the sight! The backup plan was to loosen the rear sight blade and slide it higher. I also noted that the whole rear sight unit needed to be snugged down, so that was also done.
These .177 Eley Wasps are from the same timeframe as the Meteor rifle.
Loosen the 2 screws and slide the sight blade up to raise the point of impact.
Before we proceed, a word about .177 Eley Wasps is in order. Many of you know that the 5.56mm (.22-caliber) Eley Wasp is a particularly fat .22-caliber pellet. It’s often the best in vintage airguns whose bores are on the large side. But the .177-caliber Wasp is not an oversized pellet — at least not the ones I have. I often choose these pellets for guns with larger bores such as the Meteor, forgetting that these aren’t the best or biggest .177 pellets around.
I shot only 8 pellets at the target because the group grew to 3.559 inches between centers, and it didn’t seem worth my time to finish. But that wasn’t all I noticed. Most of the pellet holes are ripped out to the right, as if the pellets were not traveling straight. We know from the previous velocity test that this rifle now shoots fast enough to not tear target paper when the pellets pass through, so this tearing had to have been caused by the pellet’s orientation and not its velocity.
It only took 8 Eley Wasp pellets to convince me that this was not the right pellet for the Meteor. Notice the tearing of the paper! It’s all in the same direction. I’m cutting off parts of the bulls in this photo because they contain another group from another pellet.
Crosman Premier lite
These results were enough to convince me to use modern pellets in the Meteor. The next pellet I tested was the Crosman Premier lite. This time, I fired all 10 pellets, and the group was much smaller than before, but it still measured 1.73 inches between centers. That’s horrible for any air rifle at 10 meters!
What was even more surprising is the fact that the Premiers also tore paper to the right of the main pellet hole. In fact, they tore in exactly the same place!
It looks like 9 holes, but there are 10 Crosman Premier lite pellets in this group. It measures 1.73 inches between centers…and notice the tearing of the target paper in exactly the same way that the Eley Wasp pellets tore it.
If the pellets were tumbling in flight, the tears would be randomly scattered around the main hole because the tumbling pellet would change its orientation all the time. But because they are all in the same place, it looks like the pellets are tipping as they exit the muzzle and flying straight to the target in that tipped orientation. Hmmm! Have to think about that.
Air Arms Falcon
The next pellet I tried was the Falcon from Air Arms. I selected this pellet because the heads were sized large, at 4.52mm. They have the largest heads of any .177 pellets I have.
They put what looks like 9 shots into 1.863 inches between centers. Once again, several of the holes are torn on the right side.
The final pellet I tested was the RWS Hobby. This is a large wadcutter that sometimes is very accurate at 10 meters. But not this time. Ten went into a group that measures 2.05 inches between centers. They also tore the paper to the right of the main pellet holes.
I knew something was wrong with the rifle because these pellets all fly at different speeds. There’s no way a tumbling pellet can tear the paper in exactly the same place when they all get there at different times. For even one single type of pellet to do that is hard to believe, but for 4 different types…it’s impossible. The pellets have to be leaving the muzzle tipped on their edge and remain in that orientation all the way to the target.
I know that most of you have guessed what’s wrong with the rifle by this point, but I hadn’t. Of course, I didn’t have someone pushing my nose into the facts like you have in this report. It wasn’t until my buddy Otho came by for a visit. I showed him the targets (because he has an interest in the Meteor, as you recall), and he said, “I’ll bet that barrel needs to be recrowned.”
Oh, my gosh! How could I fail to see that? Of course that was the problem. When I brought out the Meteor for him to look at, he saw it right away. I bet you will, too. The muzzle is backbored by more than an inch; but with a tactical flashlight, we were able to look down inside.
See the dark spot at 10 o’clock? It appears to be a nick in the muzzle. How it got there I don’t know, but it should be fixed.
The saga continues!
Yep, this Meteor is like an old tractor, all right. Just when you think you have the thing running and looking spiffy — the magneto quits. These days, there’s only one old man in Kansas who can repair them. Actually, I protesteth too much because I really enjoy working on this gun. It wasn’t made in China, yet it has turned out to be even worse than most of the very poor-quality Chinese airguns I’ve tested in the past.
In truth, there’s a lot of great engineering in this rifle, as well as a ton of abuse. You BSA Meteor owners out there know that I’m not purposely beating up your favorite airgun. It’s just that it challenges me at every turn. But that’s a large part of what makes this hobby interesting. After all is said and done, I’m not upset.
OK, take that report on a Friday and run with it! Remember, I’m on my way to Las Vegas and cannot answer as many comments as normal.

Falke 90 underlever rifle is a German spring-piston gun from the early 1950s.
Cometa Fusion .22 update
Before I begin, I want to update you on the Cometa Fusion Premier Star report that I’m doing. The fifth accuracy test failed because the scope moved — again! Kevin sent me a special base that people on the internet were having success with, but alas, it did not stay put on the rifle I’m testing.
The vertical scope stop pin on this base is 0.137 inches in diameter, and the stop pin hole on the rifle is 0.111 inches; so, the stop pin cannot enter the hole. As I’ve said many times in the past — no amount of clamping pressure, alone, is enough to hold a scope base from moving, except when BKL mounts of the correct size are used. Unfortunately, I don’t have any of them with enough droop to compensate for this rifle.
I do, however, think this mount base will work because it does have the amount of droop that I need for the rifle. When I come home from the SHOT Show, my plan is to grind the base pin thinner so it will fit into the hole. If that doesn’t work, I don’t know what I can do that I haven’t already tried. Remember, I’m doing this because I believe the rifle is accurate and would be a wonderful value if I can just get the scope to stay put.
On to the Falke
I started this report on the Falke 90 because I hadn’t really shot it that much since getting it in 2010. Vince fixed it for me, and Mac did the accuracy test. I got the rifle back from Mac, but there wasn’t anything to do that hadn’t been done. So, this year I had the stock restored, and that was a huge project for Doug Phillips at DAMAGEDWOODSTOCKS. Then, I thought I would test the rifle as though I’d just bought it because, essentially, that’s what happened!
I learned in Part 2 that the velocity and stability of the rifle were affected by the depth the pellet was seated into the loading tap. And the Falke’s tap is a small one, compared to other taps I’ve used, so the seating depth is more variable in this rifle with most pellets. Most pellets fall into the tap and stop at different depths, and often they aren’t in far enough to close the tap without damaging the pellet. That will become important in this test.
The first pellet I tried is the one that I always shoot in Hakim rifles, which are very similar to this one. It’s the 14.5-grain RWS Superpoint. I expected to get the same performance from this rifle as I got from more than a dozen Hakims over the years. Alas, that didn’t happen. The tighter loading tap on the Falke meant I had to seat the pellets manually to clear the tap, and the results at 10 meters, rested, were not that good. Ten shots made a group that measures 1.124 inches between centers. As you can see, it’s an open group with scattered hits that tend toward the vertical.
JSB Exact 15.9-grain
I won’t even show a target for the JSB Exact 15.9-grain domes because the pellets went all over the place. I didn’t even finish the group.
Next, I tried RWS Superdomes, but they weren’t much better than Superpoints. They did give a smaller group, at 0.861 inches between centers, but that’s only good by comparison. I’m looking for better accuracy from this Falke because I think it’s there. Oh, yeah, also because Mac got much better accuracy in his test!
The iron sights are fighting me
At this point in the test, I had to admit the iron sights on the rifle were working against me. I simply could not adjust them high enough to get the pellets centered in the bull at 10 meters. I remember that Mac used a red dot sight he mounted to the rifle, and I may need to do the same to get the groups I’m looking for. That will have to be another test because this one was already taking a lot of time and I wasn’t finished.
What did Mac do?
When Mac tested the rifle he found that the obsolete 5.6mm Eley Wasp pellet shot best. In fact, it wasn’t close. He got a group with Superdomes like I did, though he shot from 15 yards rather than 11 (which is 10 meters). So, the next pellet I tried was the Eley Wasp.
Eley Wasps are much larger than other .22-caliber pellets, so imagine my surprise when the first one fell deep enough into the tap to not require seating. After that, though, I seated every pellet to the bottom of the tap. Perhaps this is why Mac was telling me to do this! I didn’t appreciate it during the velocity test, when deep seating made the velocities more variable; but in the accuracy test, look what happened! Nine of the 10 pellets went into an almost single hole that measures 0.695 inches between centers. And the 10th shot is way low. It opens the group to 1.029 inches. Want to guess that this is the first shot that wasn’t seated deeply? I don’t know if it is, because I didn’t look at the target before I completed it. I only saw this when I went downrange to retrieve the target for photography and measuring…but I think it is.
Nine in 0.695 inches, and one below opens it to 1.029 inches. I don’t know, but I’m guessing the one I didn’t seat deeply was the stray shot.
What have I learned so far?
The Falke is certainly a different air rifle, and it doesn’t turn out to be what I thought it would be. I like the feel of Hakim rifles better than this one. They seem to shoot smoother, and their triggers are easier to adjust. Still, I don’t think I’ve completely mastered the Falke 90 yet.
This reminds me very much of a .22-caliber BSF Bavaria S54 taploader I used to own. It had a huge diopter rear sight, yet couldn’t hold a candle to a plain old Diana 27 for accuracy. Just because a rifle is a rare and vintage gun is no guarantee that it will also be a smooth and accurate shooter.
I do think that I need to try the Falke again, and this time with a dot sight mounted. And I’ll deep-seat Eley Wasps from the start and not worry about whether or not there are other good pellets.
This is a learning experience — that’s for sure!

Falke 90 underlever rifle is a German spring-piston gun from the early 1950s.
This report is my test of the .22-caliber Falke 90 underlever air rifle I acquired a few years ago. When I got it, the rifle wasn’t working, so blog reader Vince offered to fix it for me. After he finished, he took it to my friend Mac, who tested it. I’ve owned this rifle for several years and never really tested it myself, and I thought it was about time to do so.
I recently had the stock restored by Doug Phillips, who did a wonderful job. Now, I have a nice-looking underlever spring rifle as well as one that works well, so today we’re going to look at its velocity. And we’re going to do more than that because Mac told me some things about the gun that have shaped today’s test. Why don’t I share them with you now?
The Falke 90 is an underlever, which means there is a separate lever to cock the mainspring. In the Falke 90, it’s hidden by the stock — very much like the BSA Airsporter and the Hakim, which are both related to the Falke. All three rifles are loaded through a tap that rotates open automatically when the lever is cocked. That provides a place to drop the pellet, nose-first. Then the tap is manually rotated closed, the pellet aligns with the breech (in front) and the air transfer port (behind the pellet). Let’s talk about that tap for a bit.
The tap opens by a mechanical projection on the cocking linkage that pushes the tap as it passes it during cocking. I think the remarkable thing is that it stays in adjustment over hundreds of thousands of shots and scores of years of use. My tap is still aligned perfectly, so I don’t have to do anything except drop a pellet nose-first into it and then rotate it closed to align with the barrel.
There can be a problem with a tap, however. The pellet chamber in it can be so exact that pellets don’t fall all the way in when they’re just dropped in. This is what Mac pointed out to me about this rifle. My taploader experience has been with the Hakim rifle, which has a generous pellet chamber and seldom has a problem — unless the pellet skirt is bent. Then, the pellet won’t fall into the tap’s pellet chamber as far as it should; and when you rotate the tap closed, you’ll catch and bend the pellet’s skirt. But the pellet chamber on the Falke 90 tap is very small and may or may not accept the pellet as far as it needs to — to clear the receiver when the tap is rotated closed.
Mac told me to watch for that problem and to make sure each pellet made it into the pellet chamber as far as it needed for clearance. He advised me to use an instrument to push each pellet as far into the tap chamber as it would go — thus clearing the skirt when the tap rotated closed.
This pellet was dropped into the tap and failed to enter the pellet chamber far enough to clear the end of the pellet skirt when the tap is closed.
Here the pellet has been pushed into the tap as far as it will go. This pellet will easily clear the gun when the tap is closed.
This tap business got me wondering about the affect on velocity. Would a deep-seated pellet be better (faster and more consistent), or would a pellet that has just been dropped into the tap do better? I’m sure you can come to your conclusions quickly enough, so let’s test a couple pellets and see what really happens.
I began shooting RWS Superpoints when I got my first Hakim. They seemed like the perfect pellet for that rifle because they have thin skirts that will flare out from a smaller blast of air and also because they just dropped deeply into the Hakim tap. Other pellets were too small for the Hakim tap and failed to produce adequate velocity because much of the air compressed by the piston slipped past them in the barrel.
In the Falke 90, however, it’s a different story. The pellet chamber in the loading tap is very small, and Superpoints do not usually drop in far enough to close the tap. Many of them need to be seated mechanically. So, I tested them two ways. First, as just dropped in but not pushed deep and second as pushed into the tap as deep as they would go.
Very few of the pellets fell into the tap deep enough by themselves to close the tap, so even in the first test there was some pushing that had to take place. Perhaps 6 pellets had to be pushed into the tap a little while 4 fell in deep enough on their own. This string of what I’m calling unseated pellets averaged 476 f.p.s. and ranged from 465 to 484 f.p.s. That is a spread of 19 f.p.s. At the average velocity, this pellet and loading method generated 7.3 foot-pounds of muzzle energy.
Next, I tried pushing the pellets into the tap as deep as they would go. Now, I bet you think they’re going to go faster than the unseated pellets. Right? Well, they did one foot-per-second faster! Yes, the average for seated pellets was 477 f.p.s., and the spread went from 461 to 493 f.p.s. So the range was 32 f.p.s. And the average muzzle energy was 7.33 foot-pounds. Not much difference, is there?
JSB Exact RS pellets
The other pellet I tried was the lighter JSB Exact RS pellet, which in .22 caliber weighs 13.4 grains. This is a pure lead pellet, like the Superpoint, and it also has a thin skirt. But the Exact pellet is smaller than the Superpoint. These pellets fell into the tap far enough to close without any damage every time.
On the first test, where the pellet was just dropped in, the Exact RS averaged 453 f.p.s. The range went from 445 to 463, so a spread of 18 f.p.s. At the average velocity, this pellet generated 6.11 foot-pounds. And no mechanical seating was necessary.
On the second test, where the pellet was pushed into the tap as far as it would go, this pellet averaged 457 f.p.s., but the spread was much larger — ranging from a low of 448 to a high of 484 f.p.s. So, the velocity varied by 36 f.p.s. At the average velocity, this pellet produced 6.22 foot-pounds of energy at the muzzle.
What do these numbers tell us about the rifle?
For starters, I hope you realize that this was not a normal velocity test that produced standard numbers. The way the pellet fits the loading tap has a tremendous effect on the outcome. I believe that will probably carry over into the accuracy test, as well, so I wanted to try one more test. What would happen if I flared the skirts of every pellet before loading it into the tap, and then I pushed each pellet to the bottom of the tap? Wouldn’t that give me the best sealing of the pellet to the bore? Mac thought it would. But only one way to know for sure. I had to test it. And I decided to test both pellets, as I could see no compelling reason to choose one over the other.
RWS Superpoints flared and deep-seated
Superpoints averaged 474 f.p.s. when their skirts were flared, and they were then seated as deep as they would go into the tap. That puts them in about the same place as the pellets that were just dropped into the tap and those that were intentionally seated deep. But here’s where it gets interesting. The range went from a low of 464 f.p.s. to a high of 504 f.p.s. I’m not looking at the 40 foot per second velocity spread as much as I am the four pellets that topped 490 f.p.s. Clearly, flaring the skirts has an effect, but I must not have done it uniformly enough to make a difference.
JSB Exact RS pellets flared and deep-seated
The JSB Exact RS pellets are more flared to begin with. Even though their skirts are not quite as wide as those on the Superpoints, they lend themselves to flaring much better. These pellets averaged 487 f.p.s., which is a 20 f.p.s. increase over just seating the unflared pellets deeply. The range went from a low of 465 f.p.s. to a high of 501 f.p.s. Four pellets were at or above 500 f.p.s. Again, there must have been some inconsistency in the flaring, but the RS pellets did seem to respond better to the process.
Normally, I report on the trigger-pull in the velocity report, but I’m not going to do that today. The Falke 90 has an adjustable trigger that works on the sear contact area; and during the test, the trigger-pull went from being very light to not staying cocked. So I adjusted it heavy for safety’s sake. A taploader is safe because, until the loading tap is aligned with the bore, the pellet will not move; so when the gun fired on its own several times, there was no problem. But if I were to adjust it to a light pull, I might then close the tap before the gun is on target — and that’s dangerous if the gun then fires on its own! So, I’ll adopt a procedure with this rifle of not closing the tap until the sights are on target.
I’m also having difficulty with the trigger because the trigger return spring isn’t sufficient to push the trigger blade into lockup with the sear. When I cock the rifle, I also have to push the trigger blade forward to engage the safety. That may be because the new wood is a little tight in the trigger region. It’s something I need to look at.
The rifle is shooting well thus far, with the exceptions noted. The next report will be accuracy, and for that Mac has set the bar very high.
