hogs can be a real P.I.T.A. https://www.midwayusa.com/product/5...cf-430-diameter-310-grain-flat-nose-gas-check
MOLD DC C 430-310-RF
sized .430 and loaded over 21 grains of h110 does a great job
yeah a 357 mag works reasonably well if properly loaded.(assuming your a decent shot of course!)

H110 powder and a gas check hard cast bullet like this works in a 357 mag just fine if you can shoot accurately
12-13 grains of H110 , or 296 powder generally works under the NEI hard cast 171 grain bullet linked above
use 95% WW allow and 5% pure tin
