I made a huge mistake. I made a big 2" diameter circle and a Quarter (coin) sized one. JSB 18.1's all hit dead on or High. FTT slightly low (1") but within 1" 4 shots. The 21.1 5.51 Cuda Match, way off high & low but just too heavy. The FTT 5.54 did tightest and unknown JSB 18.1 hit dead center but 1" higher than POA
So what, when a good match for barrel & power is found do we call a good group at 32 yards steadied on a rail with a .22 R1?
