I was just down in Miles City, MT to do get acquainted with a new muzzleloader propellant. This nitro cellulose based powder burns cleanly and uniformly. Accuracy with a new TC Triumph was very good at the 100 yard range. After 20 shots the barrel cleaned completely with five moist patches. Even after shooting and removing the breach plug there was not much residue left in the bore. Lots of smoke, about same velocities as other black powder substitutes, very easy to clean. Looks like we have another choice for our front stuffers.
