[QUOTE="gilk1, post: 2616899, member: 38214"] Accuracy and velocity spread are also concerns . For example, if your target size is 5” diameter, a 1moa rifle is limited to about 500yd based solely on accuracy (other factors like wind, vel extreme spread, and shooter ability) may reduce that further. That same rifle with a 1/2moa load doubles it’s effective range to 1000yd (actually less than double due the parabolic dispersion pattern caused by aerodynamic drag - the same 1moa group at 100yd is larger than 1moa at 1000yd due solely to deceleration). High extreme velocity spread will also open your tight group at extreme range in the vertical axis. [/QUOTE]
