Re: Black Hills 308 match powder and charge weight?
Yup, don't look like AA2230 for sure.
Ball C-2 also looks like that, but I think it's *usually* a bit darker than WW-748. Both have the occasional flattened sphere in there.
Saw an article in Handloader in the mid-1980s by some benchrest nut who was running his 748 through two sieves to separate out the small granules and the large granules. Testing showed it did reduce his velocity spreads, but I don't remember if it helped his accuracy any. Shooting .308, IIRC, but might have been 6mmBR.
