I re-load 9mm 40 cal .308 and 22-250 everything is fine except when I reload my 22-250 the bullets do not seat and the bolt will not close I have to tap the bolt to get it open at first I thought it was a bullet thing but I can put just the brass into the barrel and that won't seat either it'll stick out a bit . The brass measures out but I haven't measured the shoulder and some say that might be the problem and it needs to be set back if that's the case how does one go about doing this ? All your help is greatly appreciated.
