I was prepping some Hornady brass and after checking length and case mouth I started priming them on an old Rock Chucker. I found that in about 60-70% of the cases I would have to retry to set the primer to the proper depth and was amazed at how much force was required. A question pops into my mind if this would affect accuracy out at extended distances. If I were hand priming these I don't think I could have set the primer to the proper depth. I was using some Fed 210M primers and wondered if those primers seem to run on the outside of sizing or if the brass was just cut with tight pockets???
Hopefully after shooting these 100 rounds thing will loosen up but not sure....................
Maybe switch to a different brass manufacturer.
Just talked to a tech at Hornady and he assured me that the brass was withing spec without looking at any lot numbers and that there wasn't much he would do. After talking to him I get the feeling that if I were to send a case back to them after firing, I would be told that it was withing spec.
