[QUOTE="sambo3006, post: 182178, member: 2740"] Great group! For all practical purposes, one minute of angle (1 MOA) equals one inch at 100 yds, two inches at 200 yds and so forth. So what stormrider said basically means you shot the equivalent of a 1/4" group at 100 yds--although what you did would actually be harder due to wind drift and velocity differences from shot to shot at that distance. Your vertical dispersion is a better indicator of load precision at long range than horizontal spread due to wind drift, assuming your barrel is free floated and is not excessively hot during shooting.
