Pistol? No way. As others have stated for rifle it's possible if you're chasing 10ths of an MOA. I do like the Redding FL bushing dies and competition seating dies for .308/6.5CM/338LM. Pistol its Dillon Carbide.
Seems like it. I recently switched to wet tumbling and all the brass is so damned clean I’m noticing a lot more. I’ve probably loaded tons of them without even knowing.
That's the problem I'm not sure if it's my brass or not. I usually go out once a week and shoot about 200 rounds of pistol. If I'm shooting in one of the outdoor bays there's a lot of other brass laying around. If I'm shooting in one of the covered ranges it has a concrete floor and everything I sweep up is my brass. After tumbling I find a few of these and I'm sure several have made their way into the case feeder. None of my loaded rounds have any issues. I was just curious and the line reminds me of the ring you get on rifle brass at the head before you start getting case head separation.
If I catch em I throw them out.
It’s not dotted line they generally are. Looks like a line from a crimp but left after the fact.
no hump. Could be from a previous crimp, but it’s not on all cases. All my rounds are tapered to .375 for the last 7 or 8k.
