I'm running my 16.5" Remington 700 in a Greyboe and I've got no complains so far.
Getting .75" groups pretty consistently with FGMM 168gr which is fine with me (for now).
Welcome to the hide! I'm a new member as well and I've already learned SO much from browsing the forums.
What kind of gear/rigs are you guys running at Georgia SWAT? R700?
