I am developing loads using IVI brass and 150 grain fmj's. Anyone develop a good load for 18.5" barrel? 43 grains of H4895 with CCI 200 primers seems to do well and 44 grains of W748 with a CCI 250 primer is very consistent. Velocities are in the 2600fps range. Anyone else have a good load to try in this barrel length (remember, military brass)??????
