most USMC sniper rifles are Rem 700s... and most are chambered for .308... you will find some .300 WinMag for "special occaisions"...
I know the gurus at Quantico have been workin' on a 6.5 x.308... proving to be lethal in an AR-15 configuration... don't know if they are using it in the bolt guns...
Thanks. That's good to know.
I absolutely love my 700 in .270, (although the last few times I went out I used black powder).
But that 700 in .270 just feels *right* when you pick it up...I favor it over everything else I own, next in line being my over under SKB 12 gauge with 26" barrels, which also feel pretty right.
