Gentlemen, I understand about shooting for groups to check the accuracy of a rifle, handgun or the shooter. My Grandfather taught me that over 60 years ago, the Corps reinforced it over 50 years ago and a lifetime of shooting has taught me quite a bit. Have accurized rifles, handguns and developed loads that enhanced the guns capabilities. The rifle that I used for this will consistently shoot 3/8" to 1/4" groups using SK Rifle Match at 50 yards. Some days even better and some days a bit worse depending on conditions and the loose screw behind the trigger. All that said, a group like this is something to behold and marvel at in my book. The fact that I could do it after having the cataracts in both eyes fixed amazes me and makes me very happy...........
