Bad seating

[ReeferMac]

Putting some rounds together for this weekend, had one produce a little push-out on the brass?

Is this round safe to use? It's only on half the shell. Looks like it was seated a little crooked (brass pushed it back straight)?

It probably will not chamber-I wouldn't try to fire it-chalk it up to experience.If you have a bullet puller you could save the bullet and powder.

That's what I get for loading during the Stanley Cup... (go pittsburgh! )

You diagnosed it correctly. Check and see if it passes the "plunk" test... Pull the barrel from your M&P and see if it just drops in the chmber. It will make a plunk noise as it goes in. It should fall in and fall back out. If so it will be ok. If not junk it.

Yeah, don't use the round. The brass where it's deformed is stretched thinner than normal now.

Just a couple of weeks ago I had a guy in the shooting lane next to me at the range blow his CZ ( polymer frame) apart in his hands from a bad casing... All the pressure went out the side of the casing instead of down the barrel. I personally wouldn't risk trying to fire it!

Thanks, I'll give that a try, but probably pass on this round (and one other I noticed).

I was inspecting some of the other rounds a little more closely, and was surprised to see some deformation in a few others (though not nearly this severe). Frankly, I'm kinda surprised? I thought the seating die was supposed to straighten the bullet better before pushing into the case? I'm not bragging, but I've aimlessly seated ammunition before while watching TV/Movie, and I'm positive I've sent crooked bullets up into the press, w/ the expectation that they will get straightened out...? Can't say I recall seeing one pushed out this bad, however?

Shrug... 198 rds to use when I'm at the indoor range @ ORSA on Sunday (got key, now I've gotta pull RO duty, schucks... )

Thanks again for the help everyone.

I believe it is cause by thick brass check the head stamp on the and see if there all the same . Had this happen on some 300 black out brass I converted the weird thing is it passed my chamber check gauge but wouldn't chamber in my rifle turned out it was only foreign brass that did it.

Well was that the cause?

I think it was just bad alignment when seating the bullet. If I'm more careful during that stage, it doesn't seem to happen.
