300mp?

[like it all]

Anyone familiar with this powder? I ran across 44 mag loads calling for it in the Alliant loading data. Looks to be a magnum pistol powder for heavy bullets. Is this another H110/296 ? :)

A it slower than 296-h110, does not need Mag primer.

Try it, you will like it awesome velocity in .357 magnum. And with a standard primer too. Over 1500 fps with a lyman 358156 in a 6.5 inch Blackhawk. Started at 17 grains and worked up to 18. Boolit weight with my alloy was 164 grains
