reloading some bullets i cast from wheel weight lead for 45-70, they are 340 grainers. I've always loaded jacketed bullets in the past and am wondering roughly how fast i can push these before i start loosing accuracy or leading up the barrel. figured i'd start with 37 grains of re 7 and work from there. don't have exact data for this bullet weight but it is well below max judging from data for 385 grainers. should be in the neighborhood of 1500-1600 fps.
MY QUESTION - is that too fast for ww alloy.
