I've posted threads on both Campfire & SnipersHide in the last few weeks asking about using the same powder in the 204 & 223 (cuz I'm cheap and like minimal specialized components).
Seems like the 39 Blitzking is quite the popular bullet for the 204, along with Varget, H335, RL10x, BLC-2, and Benchmark powders.
Sorry I don't have any recipes for ya - haven't started rolling any myself yet.
