When seating XTPs on a Rockchucker press do you guys have better luck with the flat seating plug or the concave. Am loading 357 Sigs not that I think it would matter much if it were 357 Sigs or 357 or 40s. But just talking to someone who asked which should make more accurate lengths and not close the hollow points at all. Using RCBS Dies.
