BHN For cast bullets for 375 Win
Can any of you guys give me a decent BHN for an alloy to cast bullets for my 375 Win? I'll probably be pushing them about 1800 - 1850 fps.
i have a bunch of pure lead on hand and have some linotype on the way

Ive used 4%-5% TIN, and 95% WW alloy with a gas check bullet in my 375 H&H for decades
ww 748 powder works ok.
RL7, and IMR 3031 all work ok

I cast hot enough to look mildly frosted over the total surface and drop the hot bullets into a 5 gallon bucket of cold water
you want a MINIMUM BHN of 18 or harder 19-20 is about ideal for accuracy, at about 1800-1900 fps, 18-19 performs decently on hogs/deer with proper shot placement, if you don't get the accuracy you require with a gas check bullet sized and properly lubed at about .377 try a bit harder bhn, but thats rarely required, obviously powder burn rates and rifling twist rates, bore smoothness, effect the accuracy
