[QUOTE="LaHunter, post: 1071076, member: 54963"] I have a M700 7mm rem mag with a Krieger barrel on it. The rifling twist rate is 1:9.5". I have tried to get my rifle to shoot the new ABLR 168 grain bullets without success. The groups that I get at 200 yards are pretty erratic (1 moa up to 2+ moa). I have tried seating depths from touching to .05" jump with no success. I am wandering if my rifling rate of twist is not quite fast enough?? I would like to get some opinions from those of you with experience shooting 168s and what rifling twist rate you have used. Also, my rifle shoots the AB 160s great with IMR 7828 at 66.5 grains, which pushes the bullets at 3100 fps. Opinions appreciated. Thanks [/QUOTE]
