SR4759 was,,don't know if it still is,,very popular for cast bullet loads in the 45-70 Trapdoor. Very accurate. Usually loaded, but not always with a wad over the powder charge.
Over powder wads are not the popular thing to do these days. But not so long ago it was.

SR4759 still popular in the 30-06 with cast bullets.
Loads are listed in any bullet weight range from 122 to the 210 in the Lyman cast bullet manual IIRC.
Velocity is in the range of 1600 to 2300+ fps depending on the weight of course.
Pressures are less than in loads using fast burning powders like RD,Unique, PB, ect when compared side by side using the same bullet weight.
..and the SR4759 minimum load velocity is usually about the max velocity of what one of the fast burn powders can achieve.

I use it in my Sedgley 30-06 sporter built on a low# '03 action.

Lots of cast bullet shooters like the powder too.
