I've used either 777 or Goex Pinnacle in my Pietta Remington, Ruger Old Army, Dance and Brothers, Uberti Walker, Uberti 3rd Model Dragoon, and Palmetto Dragoon Pistol carbine all with good results. I've only used hot soapy water to clean them and Ballistol or Breakfree CLP to lube them; I didn't have any weird reactions to it or deposits from the BP substitutes. If I get lazy and don't clean my SS Remington or Ruger, I notice gray fuzzy stuff on the forcing cone after a couple of days. (I clean my blued guns the evening after I shoot them.) Pinnacle and 777 "self lubricate", I don't have to use greased wads with them; I use a dry wad to wipe the bore, just in case. The fouling is greasy and so easy to clean off, I use a baby wipe on my Remington's frame and it cames right off. If I only shoot one or two cylinders, I only have to soak the cylinders in hot soapy water to get the fouling off. I run hot water down the forcing cone and run a nylon brush down the bore followed by a wet swab and then a dry swab and it's shiny clean.
When I run out of Pinnacle, I'm going to use KIK in my revolvers and use lubed and dry wads together again.
I've loaded and fired about 100 rounds of .45 Colt loaded with Pinnacle. At first 30 grains with a 245 grain wadcutter, now 25 grains with either a 200 grain wadcutter or 200 grain round nose with a dry felt wad to fill the space. I'm going to try the same load in a Schofield case, minus the felt wad.
