I see on Alliant's powder data site they have a new magnum pistol powder listed with load data and velocities that blow any other powder velocities out of the water that I have seen in a handgun. Kind of jaw dropping to me.

Anybody tried any 300MP?

Hodgdons data for H110/W296 is within a couple fps of it in the 44 & 357 mags with 240 and 125gr bullets and with the same BBL length. I didn`t bother to look any farther

They might have actually copied H110/296 powder? They copied Hodgdon Clays powder and call it Clay Dot. I wouldn't put it past them.

remember when rl-17 first came out? it was supposed to transform several more sedate chamberings into ultra mags and all that?

well, i tried it in a few chamberings and found it to be a great powder. however, it didn't do anything for velocities that i wasn't already getting.

btw... when you go buy your 375 ruger, just go ahead and pick up a pound or 2 of rl-17... phenominal powder in that application...

So has anyone actually purchased and tried this powder yet?
