Are you saying its safe to shoot rounds with high primers, but to just realize the feeding issues?
Yeah, it technically is safe to shoot them, but I doubt they will ignite on the first strike. The first strike usually finishes seating the primer, the seconds sets them off. If they are very high, they won't even feed.
What I was saying above, was that don't worry about seating them when you are loading the round. He (Jxman25) was worried about setting one off when he was seating the primer in the cup (using too much force to seat it). I've loaded thousands upon thousands of rounds, some of the primers were so crushed that it actually concaved them, none ever went bang when I was seating the primer.
ya when youi see the revolver shooters get a high primer sometimes they will go all the way around again because it was seated the first time and goes off the second. Now my seating problems are solved due to my new bench
