As long as firearms have been around, there has been the quest for the mythical one-hole group, wherein X-number of rounds are fired thru what is approximately the same hole. Here is what it looks like--five rounds of Eley Tenex from the bench, at 50 yards, with an Anschutz 64 MS mounting a Leupold 6-18 x 40mm target scope. First pic is while the target was still on the target board, second shows a .22 round for size comparison.
