Case overall length
I'm using a Case OAL of 1.360
My cartridge OAL is 2.170 to 2.180 using 220gr SMK bullets
It's funny how no 2 people have the same result with a M1S upper. I use Pmags with no trouble and 30 Round DPMS mags with only a few problems. Some people get a 3-4 MOA gun and others get a 1-1.5 MOA gun. It's all over the place.
