Need some advice on a .308 reloading issue
I’m pretty new to reloading .308 (maybe like a few months into it) and I am encountering a strange issue with cartridges not chambering in a bolt action rifle (Remington 700). They’ll chamber in my M1A with no issue, and of course they seem perfectly in spec according to my case checker and calipers. I have fired them in my M1A previously, and I don’t think that they formed to my chamber simply due to the fact that all other dimensions along the case/neck are correct.
Any recommendations on what I can look for?
