I got 32 pounds of Surplus pull down IMR4895 powder from Hi-Tech.
24 pounds of it was from the same bulk batch.
That bulk powder took me a while to figure that out to use H322 data, not IMR4895 data, to get the correct velocity as predicted by Quickload, in my cartridges; 223, 243. 257RAI, 6.5x55, 7x57mm, 30-30, 303B, 303S, 308, 30-06, 8x57, and 45/70.
If you are a cook book handloader, stick with canister powder, and leave the bulk powder to the military and hard core load developers.
