All- I am looking at building a gee-whiz .458 SOCOM upper, and while I can find bolts from places like Rock River, Wilson Combat, and Tromix, I have been unable to confirm the steel from which they're made. Specifically, I am looking for one made from 9310 steel, like other high end AR bolts.
Alternatively, can anyone think of any other AR 15-compatible cartridges that share the .308 base diameter (.473") with the .458 SOCOM? Maybe I can find a 9310 bolt for that cartridge (if it exists).
