358156 hp
At large, whereabouts unknown.
Daily life has been interfering with my 458 SOCOM project, but I'm finally ready to start loading for it. One thing I want to work with is Lymans 458122 HP mould (of course). I've never experimented with is hollowpoints above average revolver velocities, and I'm a bit concerned about coming up with an alloy that will handle the SOCOMs velocities. My initial thought is 75% lino, cut with 25% 1-20 lead/tin alloy. According to the alloy calculator this should end up around 18 bhn, but I'm concerned with the ability of the alloy to expand consistently at the estimated velocities around 1900 fps. The tin & antimony numbers look like I may need to add even more tin, which is doable, or change the mix to something more like 55% lino/45% WW, & 5% tin. Crunching numbers is easy to do, but selecting an alloy that will give me what I feel I need in real world terms isn't an exact science. I'm not sure which approach to start with. The goal is for an alloy malleable enough to reasonably expand, but strong enough to hold together upon impact. I have this idea of a return to deer hunting this fall, and want to use the SOCOM upper. My last deer with this class of cartridge (45/70) didn't require expansion at all anyway. What are your thoughts?
