For a short (12.5") barrel would BM2 be better again? or is 2206H the go? running Hornady 68gr BTHP's

Lots of handy info in this thread,

Cheers,

You would need to try it and see. Conventional wisdom is the shorter the barrel the faster the burn rate you should use. Supposedly the powder that gives the fastest speed in a long barrel will give the fastest speed in a short barrel, generally mean a slower burning powder. I think the truth is somewhere in between. From what i have observed personally 2206H is a good go to powder if you desire decent velocity in a shorter barreled .223.

With 68gr HP, 26gr 2206h

16"~ 2850fps
14.5"~2800fps

Couldn't get any 2206h last time I was buying powder, got a couple of tubs of cfe223 instead. Thoughts on that? I haven't loaded any yet, would be behind 55gr corelokts for goats, 55gr campro fmj for service rifle. Have about the right amount for the projectiles I had sitting waiting at the time so shrugged and thought why not. It does look like it'll go through a thrower a bit nicer than the noodles of doom 2206h that my Lyman didn't like.. I'll do my goat stuff through the auto dispenser though, low enough numbers.
