[QUOTE="gaseous maximus, post: 1772220, member: 13886"] I don't know if any thing I say is relevent, but when I started reloading cast bullets I ran them through a simple size die that I machined. I sized them to .357 and lubed with 1/2 beeswax & 1/2 paraffin, heated in a pan. bullets were 158 gr. Ray Thompson design without gas checks. Ran them "Max" over 2400, later Blue Dot. Launching mechs. Black Hawk 6 1/2 barrel & Virginian Dragoon 7 1/2 barrel. barrels leaded like crazy,( especially the ruger), 50 shots or so and the rifling wasn't visable from the forcing cone to 1/2 way or so up the barrel. So bad that I used mercury to remove. Later I went on to a harder alloy, tried to approximate the old lyman # 2 receipe. this helped a bunch but still got some leading. which brings me to Lee's liquid Alox. Since I have been using it, Leading for me has been totally eliminated (also I've been using an alloy of 10 lb. wheelweights, 10 lb. pure lead, and 1 lb pure antimony). even after several hundred rounds, a simple brushing, and 'Im good to go. this includes 38 spc, 357, 9mm, 45 colt, and 44 mag.The 357s for example (158 gr.) I am running at approx. 1450 fps out of the virginian, ( chronographed), this is over a surplus powder, the 124 gr. 9's at over 1100.
