Keep an eye on american reloading. Get on their email list. They've had some powders that were like h335 which would fill your need
Also several aa powders such as 2320. They have their own names for pulled powders
American Reloading is the only place I've seen in the past 2-3 years with any mil surplus powders. I've picked up a few jugs of 844/846 over the years on forums but it's hard to come by and getting more and more $$.
