Over expanded brass

[lostchild]

I found about 100 300blk brass cases at the range, they are bulged just above the web. The bulge is about .025" can these be resized and reloaded? I've no idea what type of gun they were fired in (hope it wasn't a bolt action) . They look almost like they were fired in a 7.62x39 chamber. thanks in advance lost....

Pictures please!

They are scrap. This is why the were left at the range.

Without pictures its hard to say but I would offer that if they were bad enough to post about it on here then they are most likely junk like others have said.

You might could run them through a 380 bulge buster die (educated guess).

Bulges above the web are God's way of warning you to not try to make use of the brass. Working that area of the case, thinning and work hardening, is a recipe for case failure.

For how little a few 300blk cases are worth, ANY headache is not worth it...

You might be able to correct this but I would not take the chance.

You might be able to correct this [...]

Body bulges at the web can be disguised by smashing them back into the shape of a normal case, but they can't be "corrected."

That brass has been stretched, and sizing it, even roll sizing, doesn't compact it back into the same thickness it had before - it just squishes that material out towards the shoulder and neck, leaving the body thin. That work hardening that happened when they were overstretched and the MORE work hardening we do to push them back into shape means it's also thin and embrittled, at a part of the case which is relatively mobile during firing. This process is the ENTIRE driving force behind case head separations, but with 25thou bulged cases, we have accelerated that problem, and "fixing them" just hides the problem for another firing or few until that thinned wall gives way and we get separations. Pushing the belly of "glock smiles" back into the belt line with a push through sizer or roll sizer just isn't the same thing - pistol cartridges don't often fail in the same way do rifle cartridges when cases come apart. Totally different animal here.

If it's 100pc, it's $35 worth of brass if purchased NEW... $10-15 worth of reseller price on "once fired" brass... I'd rather not invite the opportunity for headache into my day for $35...

Well said and my thoughts as well. No rifle brass is worth dealing with obvious bulges. Recycle and move on.

Thanks for all the responses. I found out later they are once fired, in a 10" suppressed ( must be very over gassed AR ). Met the guy that shot them, he was shooting suppers and the brass was landing about 20' at 1:00 from him. Now I've got more scrap brass to sell.
