First of all, I don't know if this is the corresponding sub-forum, since I couldn't find where to post it
I wanted to prepare some loads to hunt last year, using only new components. The Sierra prohunter have given me good results, so I decided to use them.
I started to load the brass and the jword was not crimp, I could remove the jwords with my hand from the brass, so I kept lowering the die in the press. Until in a moment he slightly wrinkled his shoulder.
Then I put it aside and used a factory crimp of 7,65, but I don't understand why in die it didn't crimp. I could never find out what happened. I used new brass. The seater die is a 7.65 x54 lyman.
Talking to a friend yesterday, he told me that it was because the prohunter doesn't have a crimp slot, of course I don't think so, but I never found the cause. Did it happen to any of you?
