Just looked over grafs, powder valley, midway, brownells, natchez, midsouth, and finally ammoseek.
All that's really out there now is some 700X, Clay's, and Titewad.

I've got 24lbs of red dot and 24lbs of 700x on a trade/purchase for the low low.. like half a penny 5gr. Just need the 60k+ primers for it
OK, if you're going to be using 700X, let me offer some suggestions from experience. The charge weights for 700X are very low, and it's not the most consistently metering powder. so... don't try to create maximum power loads with say a Dillon powder measure, until/unless you are very sure of what level of consistency you are getting. Most folks don't realize it, but if you skip a shell on say the 550, and the hopper gets agitated for one "cycle", but doesn't drop powder, the next charge thrown will be higher. Maybe not much, but measurable, at least on my bench. Couple that with a less consistently-metering powder, and well, you're going to get a larger variance between throws. This matters not, most of the time, but if you're running on the hairy edge of "too high", it could matter. Just something to be aware of. Stay .3 gr. under max, and you won't have to think about it. But do check your drops carefully with 700X. A little bit goes a long way.
On a similar note, God help you if you try to use EIGHT hundred X in a thrower. It meters like Doritos, which is likely why it's discontinued.
Anyway, be extra careful about double-charges with 700X; charge weights are far less than half a case full. But it's a very good powder. 3.1 grains and a 147 gr. lead bullet makes for a light recoil accurate, quiet load. My CZ Tactical Sport cycles fine with 2.8 gr., with that same bullet, though various other guns will not. That's a super light load, but it still makes minor power factor with room to spare. If you're into the whole gamesmanship thang.
If you're getting 700X for $7 a pound (a penny for 10 gr.), I'd love a piece of that deal.
