And that alignment only happens as the first pellet is pushed into the breech and the alignment is done by the actual pellet as it goes into the breech from a non-aligned position?

So the first pellet can be subject to deforming as it enters the breech while it is also moving the magazine into proper alignment?  

And most (or all?) magazine fed air rifles are designed this way? Which is why serious target shooters want feed in single pellets not use magazines?

Thanks for educating me Thumbs Up :-)


Yes, that's my theory and explains why for target shooting (as opposed to hunting) many use a single shot feed from a tray which is what I'm now doing with all of my target guns.

I recently noticed when target shooting that when I and fellow competitors changed to a new mag the first shot would inevitably be a flyer.  Most of my magazines are CARM 3D printed items (beautifully made), but like most 3D printed mags takes a little bit of 'fiddling' to get into place and I believe that the first shot finalises the alignment but in the process potentially scores the side of that first pellet.  In an extreme case where the mag isn't correctly manufactured then it's possible that every pellet will be marked which will obviously affect it's performance.  Just like a misaligned suppressor that clips pellets it's not obvious unless you have experienced it before.

This is not really an issue for hunting, but definitely for target shooting (in my humble opinion).  Also, as Kruza mentions, if the return spring for the pellet drum is too tight then the pellet can be damaged as the probe is withdrawn and the next pellet is slammed into place.  On the other hand, if the spring is too weak, there is a risk that the drum won't rotate to the next pellet.

I imagine a similar problem can occur with a mechanically rotated drum.  If the drum doesn't rotate precisely then damage can occur which I now suspect was the problem with my Hunting Master AR6 rifle.

Am I right in assuming that the first round in a mag is the one that locks the mag to loaded and takes the full weight of the spring that turns the mag or is that the last pellet fired?

Yea, a good thread.

That first shot from a mag is defnitely the one to watch too.

Great thread with some rare data re damaged pellets.

Best of luck with the shooting comp and I'll look forward to more testing of damaged pellets re POI...

Thanks Kruza, it'll be a lot of fun regardless of the results Thumbs Up

I might grab that off you Mark, it's not much good for anything else so I wouldn't feel bad about taking a welder to it....

Before and after is quite extraordinary.
Crosman barrel = so useful universal tool.
I have a 6 inch scrap cut-off if wanting to make a permanent setup.
Nicely done.

Just 10m in my shed.  The pistol will be a more realistic test when I get to it.  We have a red dot pistol trophy shoot this weekend so I'd rather not swap it out until that is over.
