Hoodfu - this was with a PS90. I ran it through two different rifles, and several different magazines, pretty much the same results in every case.
I haven't ran it through my FiveSeven pistol yet, a little wary of putting known bad ammo through a plastic gun that my hand is wrapped around. I've seen the results (on gun AND shooting hand) of a kaboom before the handgun, and it's not something I'd want to go through.
The ammo was very accurate - I shot it in a match earlier this year and did well (out to 200 yards).
But the stuff makes me nervous.
On the batch I have, the noses are typical FMJ, slightly rounded. When fed from the magazine sometimes they hang up on the chamber face. While the action / springs on a PS90 aren't *too* strong, compared to other guns I own, apparently it's strong enough to set the projectiles back in their cases.
As with anything, I'm sure this phenomena can vary lot-to-lot, and as each rifle is going to be slightly different, your mileage may vary.
I didn't even notice the problem for the first full magazines. But then I had a jam. Which I'd never had in a PS90, ever. I shrugged it off. Until I had another. I noticed that round that I cleared from the action was significantly shorter than it should be.
From that point I grew more concerned. The rest of the ammo I have isn't getting shot. I have dies, and this winter, it's getting re-manufactured in to 40gr ballistic tip. Those are pointy enough they'll never have feed problems.
FWIW I have older gen PS90's (with the old trigger packs).
. Sounds like they need to start staking or crimping the bullets more aggressively, or even better, find a bullet shape that works better. You'd think AE could copy the SS197SP profile with a cheap FMJ bullet, or something
