Been out of the game a while, last eve I cast again for the first time in maybe 4 years. I used the spreadsheet on here to calculate my lead. I had a mixture of COWW and SOWW, Lyman #2, Linotype, and solder. Not sure what the solder was as the labels have long since disappeared. I put it in as 40/60. What I came up with was 93.7% Lead, 4.21% antimony, 1.97% tin, and .10% Arsenic. BHN should be 13 or so. I am planning on powdercoating them, and pushing them to 2000 fps (358 win)I think i should get pretty good expansion down to 1400 fps which should be at 250-300 yards. I am thinking this should be a 300 yard deer load. The question I have is this, is this antimony content a bit on the high side? And I forget now, but doesn't too much antimony make the bullet more brittle? Or am I within the acceptable parameters here?
