I would never believe this. Here are my results today using SK Rifle Match ammunition that has been sorted by ogive to rim length with a G3 comparator as well as sorted by rim thickness. I shot this target with Wardlows last prize possessed Swindlehurst rifle which I am glad and thankful that he never shot, for had he shot it we may have never have gotten the opportunity to acquire it in a poker game. The funny part Jeff, is that Dave makes me practice with cheap ammo and now he subsequently is afraid to give me a box of match ammo. Still waiting for the tuner to arrive in the mail and this was shot in the same configuration that it was received in.
