[QUOTE="Hondo64d, post: 1403822, member: 1390"] It tells you a couple of things. 1st, you have found an exceptional load, 2nd, you know what you’re doing behind the trigger. Rifles shoot their rounds in a cone. A number of shots is required to statistically predict with some certainty where the next round is going to go. Three won’t do it. Five is better. Ten is a pretty good indicator. Then there’s those pesky flyers. Most are so willing to blame flyers on their own ability rather than their rifle, scope, mounting system or load, when in reality they may not have muffed the shot at all. Rather, the flyer isn’t out of the group, but is actually part of the group. That is why the next three shot group may have a slightly different point of impact or maybe two in and one out. For whatever reason three shot groups have become the accepted standard for light barreled rigs. Three shots, in reality is a very poor indicator of where the next shot will go. Five is better, but still lacking. If the three shot group advocates don’t buy that though, I challenge them to this. Take your rifle that shoots those little bitty three shot groups and shoot a group and let the barrel cool. Shoot another three shot group AT THE SAME POINT OF AIM. Let the barrel cool. Repeat until you have shot 10 shots at the same point of aim. It won’t be anywhere near as small as the original three shot group. What you will have is a good indication of how the rifle really shoots and a reasonable certainty of where the next shot will go. John [/QUOTE]
