That's not a canister grade powder...meaning load data works a bit different.
FWIW, I believe you load said powder to an estimated load, pressure test and add or subtract until you get good accuracy and pressures. Then load your 100 lbs of powder into a lot.
For, the rest of us, we use canister grade powders which should provide very similar pressures from lot to lot. You can expect one can to shoot the same as the next.
