I recently purchased a new Springfield 1911 .45 I have been shooting this gun a lot (1600 rounds) in the last month. I am casting my bullets from a Lee 6 cav 230 gr. tumble lube TC. I use straight wheel weights with a little 50/50 solder added. I size and lube with liquid Alox. (lube, size, relube) Every time I go to the range I end up with what I would consider decent amount of leading in the barrel. Mostly near the chamber and on the top side of the barrel about 3/4 of the length of the barrel. I am loading with 231 to about 750 fps. I really like the load which will be used for competition. My question is, What should I do first to reduce the leading? More Alox? Don't size and shoot as cast? Try to harden my mix with water quenching or heat treating? Any suggestions would be helpful. I can live with a little leading but this is getting old quickly and have absolutely no desire to shoot jacketed bullets. I love to cast my own and still have a lot learn. Sorry for the long post and thanks again for the tips.
