Has anybody used any of this surplus powder. Advertised as being close to H1000 and US869. I would be using it in 7mm STW (162 A-Max) and 264 (ABLR, it think they are 129gr) , maybe in 300 Win Mag (210 ABLR) if it will work. Any help would be appreciated.

It's a lot slower than H1000. IMO too slow for the .264 for the 300 Win Mag.

Great powder for the STW.
