I did uniform all the primer pockets, however while squeezing so hard the plunger is leaving a half moon mark on the primer, is this ok? I have never had any issues with Norma brass, should I de-prime and return the brass, as the going rate is $140 per 100.
I had the same issue with recent lots of Norma brass in 300WM. I really like Norma brass and much prefer it over the other brands I have tried, but I haven't experienced this issue before I ended up having to prime with my Forster coaxial primer set up to seat the primers completely. No dents or other abnormalities. My RCBS did the same thing as yours. Having now shot this brass and being on the 6th reload, except for this seating difficulty, the brass is superb with excellent accuracy and ES. They are slightly easier to seat at this time. If I didn't have the Forster, I would likely have returned the brass. I am using Federal 215 primers. Winchesters seated a little easier.
