Hi there-
I'm looking at Rotometals for some of what they have, and they have an lead/antimony mix that is about 4-6% antimony. From the bumpo hardness calculator, it looks like it'll average out to 13-15 for hardness. My concern is the tin, as I've seen people mention that tin makes it easier when it comes to filling the mold (or makes it fill better). I'm attracted to this because it is 90 cent less per pound that Lyman #2. I'd be using the boolits for 158 gr SWC with my 357. What do you guys think? Thanks!
