If you want to be competitive at longer ranges don’t base your rifle on groups shot at say 200 yards. Have been working up load for my 6.5×47 and at 38.0 grains of R-15 it put 5 into .70 at 200 yards and 4 0f the shots went into .306″. This is well below 1/2 Moa but when I went to 720 yards the group was still right at the 1/2 Moa but was vertical 4″ tall! I worked up to 38.6 grains and the group went to a nice little group that measured just under 2″ and had only 3/4″ of vertical. Backed up to 885 yards and shot 7 rounds into a group that was only 2″ vertical and 5″ across! I am convinced that even though you gun is shooting tiny groups at 200 yards it still needs checking at longer ranges. The load may need adjusting a little. Then all we need is trigger time at long range to learn the wind!!
