I ordered a couple Lee 6 bangers from Midway since they are having a sale on all things Lee. One is the 200 grain plain base, the other is the 240 grain gas checked. These will be fodder for a Marlin 1895 if they cast big enough and I can get them to shoot well. I suspect I will not have issues since I got MBC's 240 grain 44 specials to shoot well in it. The plain base will be for lighter loads akin to a 44 special, but in a rifle setting. I plan to work with Trail boss with this boolit. The gas checked will be for actual magnum loads, powder to be determined but quite possibly 2400. I am trying to decide on alloys. My thinking is that the modest pressure put on the plain base will do best with range scrap plus some tin, but the higher pressure of the gas checked will probably require more antimony in the form of COWW plus tin. Any obvious issues with these alloy choices?
