I have .338 EDGE barrels with twist rates of 10, 9.5,9.3 and 9. All shoot accurately. I shoot them out to 1400 yds. and can't tell much difference except for a little spin drift. Gary

Thanks Ultraedge just wanted to see who was useing the 1/10 twist to see how well they worked with the 300 gr bullet out to 1k.Had a couple guys tell me they didnt shoot the 300 gr that good that i should have went with a 9.3 twist.

According to the Berger calculator, at 0' altitude and 0° and with a muzzle velocity of 2900 fps, a 300 gr bullet will be stable in a 10" twist.

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
