[QUOTE="Hondo64d, post: 1180795, member: 1390"] Have you ever shot multiple three shot groups at the same POA? I have done it countless times and found that three shot groups by themselves are not a very good indicator of where the next shot is going to go. I have often shot tiny three shot groups only to have the next one be MUCH bigger. If I shoot multiple three shot groups at the same POA, I get a much clearer picture of how the gun is going to shoot. And, by letting the barrel cool between those groups, I cannot blame any inconsistency on barrel heat. When doing this, I have seen, that more often than not, what might normally be thought of as a flyer really isn't, but is actually an indicator of how well that load is going to shoot. For me, three shot groups have been able to tell me that a load may not be that great, but virtually never tells me that a load IS a good one. Anyway, I have come to the conclusion that a light barrel is just not going to give me the consistency I am looking for and was hoping the collective wealth of knowledge on this and other forums might be able to answer these questions: At what contour have you guys observed that barrels become significantly more consistent than the #2 and 3 contours? Also, at what point in barrel contours will the increase in accuracy potential be REALLY difficult to measure? That might help me decide how heavy I am willing to go. John [/QUOTE]
