Smokepole for a gay guy you are one dumb Sum of Bich. Not all .308 bullets measure .308. Some will be slightly over and some under. I measured some .277 that my micrometer measured .277. Likely it's off but most are slightly off. But might be .0008 or .0006. Before you speak out so stupidly do some research. Dumb A$$.
Instead of sitting on your computer all day long on this site get out a live a little and do some things so you can report real world experience instead of spewing out crap you know nothing about.
