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!
