I've been researching loads for the 375 SM and see alot of discussion on aa1680 powder but very little data. Does anyone have reliable data using this powder. Currently I have Sierra 200 and Hornady 220 bullets.  I recently got a mold for 250 grain w/o gas check as well.

Thanks in advance,

Bob

That's near WIN296 in burn rate, so I'd start about 21 grains, which is my plinking load w/ 220 gr lead bullet

Technically, the glass is always full; half liquid, half air....
