Thanks.I blew out the side of a aluminum .45 case. I had a jam and the bullet got shoved back into the case. I shot it and that happened.
You can't get a decent crimp on an aluminum case to hold the bullet in place. Drop a box and it might suffer some setback. Check each round when loading your mags.
I used to chamber the same round in a pistol with nickle plated Hornady. (.40S&W) just asking for trouble! Nickle is slicker than "skeeter's peter." They use a stick substance to fight setback. If rechambered enough you can get setback. I pulled them and will someday get a bullet puller to "fix them."CC, Federal, etc same maker.
My brother is a mad scientist. He's reloaded aluminum, and steel in .45, and 9. Just back in 2013-14.I have reloaded the aluminum cases (.38 sp) after first use up to two times. I use low powder in em. But I shoot them in my .357. Not supposed to do that but I experiment sometimes.
I throw them away after that. Never had a problem.
Nothing 'mad' about it, I guess. (precautions) Good for your brother. Heck.Look at Elmer Kieth. One of the best. He'd load em HOT just to see what it took to...dismantle his gun. He'd figure out what loads would work and those that didn't. But, someone will always tell ya how wrong you are.My brother is a mad scientist. He's reloaded aluminum, and steel in .45, and 9.
