My barrel was 29.6'' and velocity with 65.5 grains of H-4831 was 3140 ft/sec using a rem
9 1/2 m primer.
Standard deviation for load 1 was 8 ft/sec and for the hot load it was 9 ft/sec. I tried the fed 215
and SDs went to high teens(17 to 19). Velocity increased almost 30 ft/sec and accuracy fell off
to 3/4 MOA and occasionally threw fliers.(The primer was to hot for this powder and load.
The hot load(Not recomended because it will sometimes blow the primer) was 3255 ft/sec
with the same primer.
Both loads shot well under 1/4 MOA and the only time I used the hot load was in poor conditions
and the ammo had to be kept cool.
