Ditto on Jeff Bartlet. He's a nice guy to talk to and has great powders. He must have connections from all over the world as far as bulk powders go. If you get 6 jugs of his powder he charges no haz-mat fee. 4 jugs, he will only charge a 5$ fee.
I tried a powder he had called NM-04,($40.00/5 lb jug). It was an over-run from a chineeze company. It had a burn rate of right about green dot or IMR PB. It is very usefull in shotgun and semi-auto pistol. I am using it in 9mm, 40 S&W and 45 acp. He just about out of it and there's no more available.
I also use a lot of WC 844,($72.00/8 lb jug). I got 2 jugs, one for myself and another for a friend. I use it for .223, 7-08 and 30-06 in my garand. It has a burn rate around H-335, you use H-335 data to load it.
Another powder he sells in WC-860 which is military H-870 powder. Since Hodgdon has discontinued H-870, this is where you can still get some.
WC-820 is supposed to replace H-110 and ww 296, but it has been shown to burn slightly faster, more like AA #9.
