Funny you say that, My friend got one of those Green VTR rifles from Remington last May. (the one with the muzzlebreak cut into the end and the triangle barrel.) ................anyhow, we were getting keyholed groups of 6 to 9 inches at 100 yards with 4 different types of factory ammo (150 grain, 165 grain, and 2 types of 180 grain) plus 2 homeloads. We did the whole re-mount the scope/rings/bases, tightened all the action screws, etc,boresighted, then the groups stayed exactly the same. We thought the NEW Redfield scope was hooped, so we put on my Burris fullfield II , and it was the same result.
Then I looked down the barrel of his gun, and IT HAD NO RIFLING CUT INTO THE BARREL!!!!!!! This gun escaped the factory with obviously stellar quality control. The best part is the dealer said my friend must have wrecked the rifling by shooting improper ammo, and it was a circus to get it returned.
Anyhow, I own a Remington from 1978 in 7mm mag, and its a real barn burning , accurate rifle. I guess Remington has gone severely downhill since the late 70's in the Q.C department.
