Finely got out my Pietta 51 .36 cal Navy yesterday. Had a can of FFF triple 7 that needs to be shot up to make room for a new supply of BP. Anyway this is the first time this revolver has ever been shot. I tried to starting on the lite side 10grs powder, wad, and .375 rd ball. First six shots at 30 feet was 6" high and 5" to the left. 15 grs same thing. 20grs same thing, 25grs same thing. No matter what I loaded in it the revovlver shoots 6" high, and 5" to the left. Is this what you have come to get use to when it comes to the 1851 .36 cal Navy. I hung another target and did the samething all over again. I'll give triple 7 one thing I was able to fire 48 shots without cleaning it. But what should I hold out and try with Prodex P, or dose it sound like I'm going to have to get out the file and work on the hammer.
