I’ve been looking around to see what powder the reloaders use on other forums and here’s a list of what I found is the most popular powder. The number to the right is the burn rate rank as indicated on the attached Hodgdon data sheet. Lower is faster.

H 4895 89. (Faster)
IMR 4064. 96
Varget. 102
BL-C (2). 105
W 760. 111
H 414. 112
IMR 4350. 115
RL 19. 123
H 4831. 128. (Slower)
So, the most used powders for reloading 30-06 cases are in the slower burn rate end of the scale. The BL-C (2) that I use is sorta in the middle of the group. Is there any reason that I should switch to a faster or slower burn rate to fire a 150 gr M2 bullet?
