Unique! Manuals have a variety of mininum and maximum for this powder. Extreme spread is 9 grains up to 13 grains and the edges are fuzzy. I would start at about 9 1/2 or 10 grains. Anything over 11 grain will be too hot for such a soft lead. There is always leading. It is the nature of this beast, but it should not be so extreme that more than a few extra strokes of the brush can't clean. If there is excessive leading on the lip of the forcing cone, bullet is too slow and if the lead is smeared throughout the lands and grooves of the barrel, it is too hot. Leading at the end of the barrel, it is the lube.

BN 14 is good for about 1300 FPS, but that's messy. Don't let a little extra leading stop you from increasing velocity for better accuracy. If it were me, I'd load about 9 or 9 1/2 grains of Unique, shoot the thing and if it groups better than 2 or 3 inches at 25 yards, I would be happy. That is more accurate than what I can every shoot off hand.
