When I started looking for a load in my new muzzleloader this I bought a pound of pyrodex and 777 powder form, well in my gun 777 left a minor crud ring but nothing that effected the loading and the cleaning was a breeze 2 wet patches and the crud ring was gone and that was 9shots without swabbing(just testing). But when it came to the pyrodex after a few shots the barrel was dirty to the point where it was hard to load and I found cleaning to be way more of a chore than enjoyment. This was the case in my rifle every rifle is differnent(that's what I hear anyways). Both shoot good groups but like said above 777 is more powerful than pyrodex. I don't know a app yet we just got in here a month ago so when my pound of 777 is done I will try the app well JS Gold.
APP/Shockeys Gold/Goex Pinnacle... all out of the same womb.
For inline testing, buy the FF.
For sidelock testing, buy the FFF and say a prayer you get instantaneous ignition because both grain sizes are very large&most powderflasks will not pour that stuff out -- thus the lack of sufficient powder granules under your nipple sometimes.
MyOmega loved the APP. I can hear it in my gun safecrying for it every night.

I won't feed it the APP anymore because I want (1) powder manufacturer and grain size for all my MLs from 45-58 caliber.
777 powder doesexactly that!
