been casting for and shootin a marlin since 79 and a sbh since 82.plain ww and a good lube are fine with full house loads.a bit of tin (2% works) makes a more purty,sharply defined bullet.ditto on dropping into a bucket of cold water.makes them hard enough you cant hardly scratch them with a thumbnail.they can run 15 to 16 bhn.heat treating is not needed for the 44 mag.24 gr h110 is a well published load and has worked for years for me.i went from a 240 gr rcbs gc mould to the 429421 a long time ago and never missed the gas check.that load shoots at 1725 in the marlin accurately and doesnt lead.never clocked the sbh but i dont get leading in it either.i dont even bother to size,i just pan lube.if you want a light load in the sbh i found that a 200 gr with 7 gr of 231 shoots at the same spot at 25 yds,where a 240 with a light charge shoots about 6 inches higher than the 240 and 24 gr of 110.the 200 gr nose profile makes it easy to identify which loads you have.shot 90 lbs thru the sbh winter of 82 and most of them were light loads.900 to 1000 fps makes for a bunch more fun when you can small game hunt and have somethin left to pick up and eat.i have a rb mould that i plan on a 600 fps load to sqirrell hunt with,just havent got started yet.the keith type design is a great performing bullet without expanding,on small game and for large game as well.
