[QUOTE="Bart B, post: 585455, member: 5302"] I prefer to state accuracy as what one can expect all the time. Average group size is easily bettered most of the time, but exceeded some of the time. But most folks don't like to use the largest group fired as the accuracy level, even though it's the best and most correct one to use. A half MOA rifle's one that doesn't shoot larger than that. With the exception of those few rifles with positive vertical shot compensation caused by barrel whip, all groups get bigger as range gets longer. That's caused by small spreads in muzzle velocity and bullet BC's and subtle air movements. Until someone proves that bullets know where they are in an imaginary group at mid range so the know what direction to change putting their path back towards the down range group center to make that group smaller, I'll stick with this.
