Ya'll got me to get a .50 flinter pistol. Man-o-man is that fun! I believe that I'm supposed to wrap the flint in something with some amount of pressure and not just unmercifully crank down on the poor flint. I could use a bit of help there. Like a bunch of my other "modern" shoot'n irons I don't put them away with much other than the thought that I outta clean up some day soon. This repo .50 does not seem to like that idea much and has a white with rust spot looking residue in the barrel. How bad is this and what should I do now? Last, what do you do when ya are finished for the day? PS, one of the guys in my gun smith class found out about my propensity for cannon making and gave me about 400#. I noticed a few long bars, the others were the classic one# ingots, these were considerably shinier. They were about 15# each. He said these were line-o-type. and the others wheel weights. How much rarer is line-o-type and how does it measure up? I was thinking of casting for a 9mm or .45 or... Thanks and happy fall. We only have cottonwood here so all we get is gold. Pretty though, especially with a breeze.
