I have noticed when these primer seating topics come up that noboby primes on a press. Why is that?
FWIW,
I have, or have owned, just about all of the Gucci Priming Tools. Including the 21st Century Super Precision unit which is very nice. That said I often prime with my Forster Co-Ax press. It's simple, does not require shell holders, and is just about idiot proof...
