    McGuire ballistics review

    I was able to get the 195s to stabilize in my 10 twist 300 winmag (24" barrel) running 3010fps at 6000ft elevation. Will be interesting to hear how they perform for you.

    McGuire ballistics review

    yes, was using 0.700 for the 160s and 0.800 for the 168's in my kestrel. Was spot on out passed 800, at 1040 was just 1/2 MOA off. My 28Nosler has a saami chamber and 26" barrel. I run the 160 at 0.020 off the lands, and the 168 being so long at 0.110 off the lands. The 270WSM is 0.200 off to...

    Yes, on the 270, the 0.580 is an average estimate, with my 270WSM a 0.600 holds out to 800 yards then it degrades to 0.580. I was gathering data for a huskemaw turret yesterday and the trued BC from their calculator was 0.5803.

    Today I shot the 160 (3208fps) and 168 (3160fps) out of my 28 Nosler to 1040 horizontal yards at 6000ft. I am sure the 7prc will too. I also took the 128gr 270 caliber bullet to 1040 with my 270WSM (3308fps). It is not difficult to get these bullets to shoot.

    I can vouch for these bullets having reloaded and hunted with them for 3 years in a variety of rifles from 6.5x284, 280AI, 28 Nosler, and 300 win. They have expanded on all game from antelope, deer, bear, bighorn sheep and elk at close range < 100 yds and long ranges to 650 yds. I have shot them...
