Go to your kitchen pantry and pull out the wife's yellow cornmeal. You can disperse the cornmeal in the same powder flask as your 777 and BH. Put 20-40 grains of cornmeal after the 80 grains of Blackhorn, but prior to seating the Powerbelt. Press/seat the bullet firmly, as you should be doing anyways with Blackhorn. This will turn that east-west bullet at 100 yards, turning it north and south.
The cormeal is a replacement for fiber wads that ML shooters often use between the powder and bullet. With that big, hollow plastic seat on those Powerbelts, cornmeal fills that hollow cavity better than a wonderwad and that also aids in flying straighter North-South bullets too.
(caution) Cornmeal should only be used when using "well" below the maximum powder volume allowances of your ML manufacturer. Personally, I treat every grain of cornmeal added, as being that of blackpowder. A little goes a long ways. You may only need 20 grains to eliminate that shotgun-looking paper target.
