网页2009年10月26日 — 2 to 1 ratio will give you 4%. I suggest 50/50 which will give you 6%. If you think that's more than you need, 2 to 3 will give you about 5%. But that is true only if the linotype is a true 4/12 and the lead is pure. You don't need to worry too much about the content of scrap.

Highest Velocity For Lead in a Rifle - Cast Bullet Forum
网页2011年6月22日 — Lead like 20:1 with tin should stay down around 1,000-1,100fps in fixed amunition. Since you are going to test for bhn, it seems to me alloy bhn hardness coencides with 1,000fps+ velocity. Where 12bhn will shoot ok at 1,200-1,300fps, and 16bhn will shoot ok at 1,600-1,650fps ok. Just a general thought.
