Best Hard-Cast Bullets for Medium Game Hunting

Hard-cast bullets for hunting medium game should be cast from alloys containing at least 2-3% tin and 6% antimony for proper hardness, typically measured at 12-15 on the Brinell scale. Softer alloys will deform on impact with heavy bone, while overly hard bullets may shatter rather than penetrate. The 158gr flat-nose hard-cast remains the gold standard for whitetail deer and similar-sized game, driving through shoulder bones and delivering deep wound channels.

For hunting applications, look for wide meplat (flat nose) designs that create larger permanent wound channels compared to round-nose bullets. A flat nose measuring 60-65% of bullet diameter cuts tissue more effectively than pointed or round profiles while still feeding reliably in most firearms. Quality cast bullet makers like Missouri Bullet Company, Penn Bullets, and Rim Rock Bullets offer excellent hard-cast hunting bullets in various profiles, or you can cast your own using proven molds from Lyman, RCBS, or Lee.

Gas check designs – bullets with a copper cup crimped onto the base – allow you to push hard-cast bullets to higher velocities without leading your barrel. For 357 Magnum hunting loads running 1300-1400 fps, gas checks become almost essential unless you’re using very hard alloy and proper lubrication. The additional cost is minimal compared to the improved accuracy and reduced barrel maintenance.

I've got those sort of hardness numbers using cleaned range scrap and quenching into a big bucket of cold water. @DsJ I have a FP mold that throws a 163gr bullet. I will be casting and powder coating a batch in the net 10 days or so. I'd be happy to send you a packet to try out if you'd like.
