I had great results using 55 and 60 gr v-max bullets in my 223 and 22-250. Both would shoot sub 1" groups with my reloads. Due to the shortages lately, I tried some 52gr a-maxes with the same charges and they seem to shoot radically different than the v-max bullets. I am using 25 grains of Varget in the 223 and 33 grains in the 22-250. Is it the twist of my barrels? The 223 has a 1 in 9 twist rate and the 22-250 has a 1 in 12. The accuracy problems are the worst in the 223. Groups are shooting 4" to the left (consistently). The 22-250 is going high and to the left about 2". I switched back to the v-max loads and bang, right back on target. Any ideas?
