strange line.

[Mike Gilpin]

This one is on my Lymann t-mag.

I’ve never sized rifle brass on my t-mag, and I haven’t used it in so long for anything that I cannot remember if it cams or not. I think it does, but not 100% certain.

Yes it cams

[JeffreyDeGraff]

I guess you could try screwing you seating die down a little more and see if that helps.

I assume this is on only 1 piece of brass? If so and unsure chuck it. That’s what old timers recommend...getting closer everyday myself. Lol, anyway they are still alive for a reason. Prob a die line though.

[Mike Gilpin]

Multiple pieces actually. I'm gonna call it a line from the die.

[Ledslnger]

Ok, if it is multiple pieces I wouldn't worry about it. Die mark.

[ReneeMicelli]

Multiple pieces pretty much confirms that it is a die mark. You should be fine.
