Primer 'crush' May 13, 2020, 02:52:37 PM When seating primers I (as I was taught to do by mentors) seat it until I feel an change in resistance and then a light bottoming out of the cup in the pocket and stop there. The resistance is from the anvil encountering the bottom of the pocket and the cup bottoms shortly thereafter. Great, in theory.... However, I find with some primer brands, I find it difficult at times to feel the anvil touch and the first real resistance is the primer cup reaching the bottom of the pocket. I find it really easy to feel the anvil touch and the cup bottom out with Fed LR primers but with CCI BR-2's and 4's it is hit and miss. With Wolf LR's, in two different chamberings, the fit is so tight that feeling the anvil touch would take skill and a sense waaay beyond my paygrade. Surely I am not the only one with this experience. Maybe it is my priming tools (K&M) but I had the same difficulties with the RCBS. FOr the record I have used no other hand primers...only press priming tools before that.
