Well does anyone use this powder? I took a chance and got an 8 pound jug and a 1 pound jug for 60 bucks. I have found some reloading recipes, but would like to have more.. It will be for a AR15, with 24 inch barrel, 223. Would like to load 55 gr spie points or boat tails. Help help appreciated.

there's always the load data on hodgdon.com
I looked there, as I'd never heard of H380, and they don't have it listed. Is this a pretty new powder?
Since I made you look for no reason, I dug it up (Speer No.9) and for 55gr 223, Remington cases, and their 55gr spitzer bullet, they suggest 27.0 gr and a CCI 450 give 2739 fps, 28gr gives 2863, and the max charge of 29gr gives 2952 fps.
They advise only going up to the middle load for semiautos.
It's a little slow for 223. It was named by Bruce Hodgdon for giving accurate results with 38.0 grain charges behind a 52gr bullet in the 22-250, a much larger round, and the manual lists 39gr as a max charge.
OTOH it is one of the few non-flattened spherical powders and will meter even better than most of those.

Yes! when I can get my hands on it. Bruce Hodgdon first used it. When a 38.0 grain charge behind a 52 grain bullet gave one hole groups from his 22 caliber wildcat (now called the 22-250), he appropriately named the powder H380. H380 is also a superb performer in the 220 Swift, 243, 257 Roberts and other fine varmint cartridges.
I am thinking it might be a little slow for .223. but if you have a .22-250 or other mid sized cal.'s it's a great powder. Just not a lot of data for .223.

Been around for years. It used to be the "only" powder for the 22-250.
7mm Mauser and 30-06. I'd agree that it probably isn't the best choice for a small capacity case like the 223.
AR has a fast enough twist to stabilize a heavier bullet (60+ grs) the H380 would work well.
