Home Forums Hunting & Shooting Muzzleloaders Best load for Omega ?

I am new to ML and just purchased an Omega.

First of all, the Omega manual says not to use smokeless, but I see lots of folks are using BH209, so I guess it's safe.

Second, the Blackhorn webpage says 120 volumetric units = 84 grains and that give you 2100+ fps.

I am assuming when you ML folks say 120 grains, you are referring to volumetric units and not true weighed grains?
