7.62 X 39 bullets measure at .310 diameter. Or at lest mill surplus ammo dose. I have shot a .308 nice not much kick .30-06 & .300win mag is like shooting 12 ga 3" mags slugs now thats a mule.
I've worked to make a lot of rugers shoot well. Only one or 2 performed. I've even spent time on the phone with ruger trying to have a rifle rebarrelled by them. They're policy is that if it shoots 5" or better at 100 yards then it meets their standard. As far as ruger rifles shooting like crap, that's not just my opinion, its known industry wide. Their heavy barrelled 77s were known to shoot well, especially the .220 swifts. The ruger #1's have even drawn a lot of criticism also. I'm not knocking any ruger owners. My favorite rifle is a 77 in 7 mag, but the fact is, they have been known in the shooting game for many years as poor shooters.Not questioning your experience with Rugers, but I have a model 77 in .270 Win that's a shooter, and I have friends who own Rugers that are shooters. I've only run across one recently that wasn't a shooter.
