I'm shooting a .308 match this weekend and have a borrowed M1A to use. I got some once fired .308 brass, a jug of I4895 and M72 bullets.
I'm trying to figure out a cartridge OAL. I don't have a comparator and am using a makeshift setup. I sized and trimmed a case and seated a bullet very long. I put the case in the chamber and pushed the bolt into battery. When I remove the cartridge, the OAL is 2.875. I got this same measurement 3 times.
Is loading .020 off the lands a good idea with an M1A? That would make my OAL 2.855. My Lyman book lists the max OAL for the .308 s 2.810.
Is 2.855 too long to seat a .308? If you're an M1A shooter, how long do you seat your match ammo?
This is my forst stab at loading .308 and this has me kinda confused.
