Default RE: NRA Tests Muzzleloader Propellants
Triple Seven FFG gave:

100 grains: 1,961 fps.
150 grains:2,166 fps.

777 Pellets gave:

100 grains: 1,731 fps.
150 grains: 2,106 fps.

Two of the spiffy new TSM pellets gave 1,850 fps.

BTW: 777 and RS (both pellets and powder) gave thelowest standard deviation ofall propellants tested. 100 grains of 777 powder gave an SD of 10.An SD of 10is very hard to attain when reloading some centerfire calibers.
