I have just acquired an 1884 Springfield 45-70 trap door. I think it one of the top ten fun things I can do with my clothes on. I traded off my Mosin sniper because hitting the mark got to be too routine, and I wanted to try something else. I am casting my own bullets. Have not seen enough results to see if I want to shoot an alloy or pure lead. Right now I need some advice on the right lube for use with black powder. I have chosen black powder instead of smokeless. Have read posts about the use of both, but have chosen black because I like my rifle like it is, in one piece. The lubes that I have on hand are; T17 Natural lube, and SAECO Green. The T17 is too soft, liquifying from body temp. Seems this lube would be better if it were thicker and I could load the grooves up with, instead of just making a slimey bullet. I pan dip the bullets in the SAECO Green, and will try them today. Do any of you who shoot black powder cartridges have any other lubes in mind that will be stiffer, and keep the black powder fouling soft?
