I asked my friend who has a .32 caliber T/C Cherokee. He said he shoots a .015 patch lubed with bore butter and this is his small game load. The recommended load for the rifle is 30 grains of FFFg which would be an equal to 25 grains of Triple Se7en in FFFg size. This is for the 47 grain round ball.

I told him what your groups were and he suggested adding just a grain or two more of powder to the rifle. He said they are a great shooting rifle...
