I have an 80's made CVA Navy 1861 44 cal bp pistol that I'm trying to tighten up the cylinder gap (currently 30-40 gap and I want 8-10). it's only getting about 84 fps average through my chrono, which I know is good. I assume a lot of gases are wasted seeping away from the cylinder gap when firing before it hits the barrel. I've probably bubba'd it to the point beyond fixing. The wedge fits all the way in pretty loose now. Thought I'd ask the experts to see if it is worth salvaging and how. Number 1 is the two metal post pins. I've attached a pic with the areas I think can be filed down but am not sure? Any help would be appreciated or to tell me it's worthless and toss it...
