Amerc I recall from the last time I separated a large quantity of brass (small primer 45 ACP also). But a quick search on the net has everything from Cyrillic stamped to WIN cases being garbage. What do you automatically reject in handgun or rifle and why?

Military brass goes into the brass recycle bucket.

Why? Because I do not have the proper tools or time to ream the crimped primer pockets.

Norma 9mm Brass - The Flash hole is extra small and will result in quite a few spent primer pull backs or broken pins when depriming your brass.

303-PP or nny headstamp

it’s always bigger diameter rim than spec. During Covid I was stuck with them being the only brass I could get ahold of and had to chuck each one into my drill and run a file to bring them down to fit in the shell holder.

I have since shot them over and over until they (20) have begun splitting and just scrapped them. I won’t be dealing with them again

Any brass stamped Blazer goes to the scrap!
