I believe that depends on whether / when the headspace is out of spec. Changing rollers will change the headspace (I think).
So you check your headspace every couple of thousands of rounds? Or just keep an eye out for the problems that too much headspace can cause?
Are there specs on this stuff, like how often you check headspace?
I check head space every case of ammo, or at the end of a day with a lot of shooting, sometimes its more than a case in a day.Are there specs on this stuff, like how often you check headspace?
