Lyman #2 was 20 lb lead 1 lb 95/5 soder so I have been told . That was old and back before soder was changed to meet plumbing codes and EPA regs . 95/5 was tin/lead . So if you get a stash of old soder , yard sale comes to mind it might contain no antomony or very little. Pretty easy to tell when it melts it looks gritty .
