@57jl, it ain't 760 and that's dangerous advice.

St Marks was spun off years ago and their relationship with Winchester/Hodgdon isn't exclusive. Alliant buy some/most/all of their ball powders from St Marks and they get their extruded powders from Bofors in Sweden I believe.

SMP 763 is the one Alliant sell as 2000-MR. Now, this is speculation - but I suspect Belmont simply buy the same stuff from St Marks. Due to the nature of canister grade powders having potentially large lot to lot variations in burn rate, one should be especially careful when working up a load. But assuming the above is correct, 2000-MR is a good starting point.

I have even read that the lot to lot variations are so large, that the powder mfg just makes "powder" and don't label it as 748, 763, 760 etc, until after it's finished and they've tested its burn characteristics to see which it came out closest to. Not sure I've seen enough to believe that - but I find it interesting.

Yes disregard my stupid mention about win 760 that was dump shit
