Thread: loose primers

Seating pressure is a bit subjective especially if you ae only using memory as a guide. There are tolerance limits for pockets and primers could be you are at both ends of the scale.
Norma is good brass but you dont know its life story i guess. On firing they will expand to fill the cup. It should be fine so long as the primers don't drop out but,you could start with a few loads a bit below your current std and look at what happens if you are worried.
For your info I have found cci small rifle primers easier to seat than winchester in the same lot of cases before and not worried,
