I use Goex Pinnacle and APP in my 44WCF and 38LC. As mentioned, I fill the case so that I get about 1/8" compression. One reason I use APP/Goex Pinnacle (they're basically the same powder) is that I don't need to use a special lube. Actually, you don't need any lube at all on the bullets. This allows me to buy regular smokeless lubed bullets, and even unlubed bullets, that are much cheaper than specialty bullets designed for BP use.
BP and the subs aren't much different than smokeless when it comes to working up a load that suits you. You must remember, though, that you cannot leave an air gap between the powder and the base of the bullet. Use a wad or some other substance to fill the gap.
