Thin wall 357?

[Riven]

I have loading for a few years but I have just started loading 357.
I have several cases with various head stamps where the projectiles will fall into the case. Even after factory crimp I can still move them by hand.
Anyone have this issue before?

Can't decide if I should tear them down and measure wall thickness or shoot singe rounds and scrap the brass.
Only have 9 like this so far out oof 100

Only time I ever experienced this was when the cases weren't sized small enough. Last wazs another guy and his .30 carbine ammo. I sized the brass and they all seated solid. Speak more about your die setup?

I had the same issue with 44 mag using campro bullets
Annealing the brass and using a Lee factory crimp die seemed to fix the issue

Not much to tell. Full length size die set to touch the shell plate. Just enough flare to fit the projectile easily. I would say I'm using medium crimp.

I will give that a try. Thank you.

I have had dies work loose in my reloading press. I snug them down with a thin channel lock adjustable now.
Just a thought to pass along in case the crimp die is working loose.

357 cases are cheap and plentiful. It's not worth hassling over problem cases. Just chuck them.

Pulled 2 apart. Mouth brass is .010 thinner than shells that seat properly. I'll toss all defective cases.
Will probably order some starline online in the future. $35/100
My local shop is $75 per 100.

What headstamp for the thin wall 357?

 

[Riven]

One was Hornady the other was PPU I think. Possibly RP.
