RCBS 7mm seating stem with berger

[Iclimb]

So I've measured, sharpie'd, and checked. I don't think my bullet tip is touching when seating the bergers but I'm getting some CBTO differences. Just wondering about experiences with seating the bergers with rcbs seating stem.

Also for the sake of another thread. Any experiences with the rcbs x dies! The theory sounds good.

I started with lee's went to rcbs and if I could do it over again I'd just buy redding bushing dies and be done with it. Venting...

I was getting poor results with the standard seating stem
contacted rcbs they made a custom stem and have not had any issues since
