I have a good buddy who had, what appears to be, a series of baffle strikes at a recent carbine match. Up to this point, rifle had about 200 rounds through it. Battlecomp was brand new. Rifle is a factory Noveske MK18, M249 barrel, 1:7 twist. Ammo are reloads: 24.5 tac, 55gr montana gold, tula SMRM primers. Here are the results:
Another buddy and I were shooting the same ammo, both 16" BCM BFH rifles, both with Battlecomps. Both shot great (infact, I took 3rd overall). I verified after the match that my Battlecomp was free of strikes and it looked like new.
I have shot that ammo since then on the range with a chrono, but no rifle matches. Well, I took a look tonight and this is what I found:
It had to have happened during chrono. I see a ton of people using this load and I couldn't find a single other instance. I worked this load up with both my 16" BCM and my 18" Loki and 24.5 was most accurate. I was hoping that this would be my go to round for 3-gun for anything shy of 200 yards.
What do you guys think? I need some help on this one. Doesn't sound like this is that common of an incurrance. Yet it seems to have happened to both us of. Common denominator: 55gr through 1:7 barrels.

Easy options first. The round could not be stabilizing properly. The comp could be lose. That's all I got.

Yep, or some of the round jackets are separating (read happens a lot with 22lr spent case made jacket bullets when pushed too fast as well).

Jacket seperation or jacket only rounds.

That's no good for accuracy, now is it? I would say it has to be jacket separation. Don't know what else it could be that close to the muzzle.
