Taking a fun day where BulletflightM popped out some pretty good data on my chrono'd 6.5 Hornady American Gunner factory ammo Larue 6.5 with Larue AR-10 lower, Vortex PST Gen 2, Hybrid 46 with Griffin Plan A taper mount and Magpul 20 rounder. Larue makes a phenomenal product. It groups at about .43 at 100 yards with bulk Hornady American Gunner. With the excellent coefficient of the 6.5 CM it makes hitting steel a relative breeze.
