[QUOTE="biednick, post: 3010165, member: 123604"] That'd be great. The more shots you have on target the less likely you are to mistake noise for an improvement. 50-100 shots isn't reasonable in most situations though, and at around 20-30 rounds you've overcome most of the statistical noise in group size. It doesn't matter what you're shooting, low round count groups aren't able to provide an accurate measure of the rifle's precision. They have their place early in load workup, but that's it. Mean radius is a different and in some cases better way to measure group size than extreme spread. It's the average distance to the center of the group rather than the extreme spread between the outermost rounds. [/QUOTE]
