In reality, people load with 15-35 grains of powder, with 20 - 25 grains closer to the average. A .015 patch is the most commonly used one with a .310 ball, but some folks use a .010 patch and 25 grains.
The smallest granulation of Triple 7 (fffg) is a cleaner burning powder and allows for more shots without as much swabbing while still maintaining accuracy.
Use smaller, thinner cleaning patches so they don't "grab" in the bore, and an extended or smaller than standard jag size may help.
These rifles can also shoot 90 grain pistol bullets/or a 103 grain Maxi with either 35 or 40 grains of powder with great accuracy out to 100 yards.
A .38 special case holds 23-24 grains of powder by volume, 777 loads are supposed to be reduced by about 15%, almost meaningless for such small powder charges, especially since these Crocketts shoot almost every powder load very well.
It's sometimes helpful to have a dedicated .32 caliber ball starter and patch worm small enough to fit into the small bore to pull lost cleaning patches out of it. TC makes a .32 worm. You definitely don't want to clean with patches that are too large or tight (unless you have an undersized cleaning jag like for .25 caliber or such) because the patches can get stuck down in the breech in some, but not all, Crockett rifle barrels. Some of them have been known for that to happen.
