Any one used any of this brass. In goggling this, it says it is Armscor  and it was manufactured in USA not Phillipines. I was gifted some brass from private outdoor range. Any one used it? Don"t plan to fully charge cases as it seems to be reloads as my friend gave me a bag of mixed brass that came from the same range session- some RP, Starline and Winchester- that was fired in a Glock.  Some reviewers said the primer pockets too shallow and off center. Just wanted to see what experiences some of my 10mm brethren had experienced, if any.
Thanks

I loaded up a hundred A USA 10mm brass that was once fired. Everything went fine. Shot like any other brass. Flash holes & primer pockets look normal. Primer pockets are not off-center and the primers seated at the proper depth. I would use this brass without reservation.

I haven't run into any headstamped A-USA. However, any brass headstamped A-MERC goes directly in the trash. It's not worth even considering reloading. It's so bad I wouldn't give it to anybody either. For the 10mm, I'm using Starline as I'm having to buy the brass as new, unused. Hard to go wrong with Starline.

Absolutely, Starline brass is hard to beat
