I have one particular rifle that bolt lock down is hard after sizing case and priming. Bolt locks down just fine after sizing only but once primed the bolt locks down hard and leaves circular scratch marks on primer where the primer would be mating up to the firing pin hole in the bolt face. If I go back and push primer down with a lot of force in a press then problem solved. Questions are: am I flatting the primer? Will switching brands of primer help? Do I have a tight headspace? Model 70 receiver and bolt , Winchester primers, Nosler and hornaday brass both and I clean pockets. No problems on any of my other reloads and rifles. Excuse me in advance for my ignorance.
