andrew375 is right.
Closest to 5744 is D060. I have both. Mine 5744 (that I bought 10y ago) was made by Lovex. I also read somewhere (Handloader?) that 5744, in its history, was made by 3 different manufacturers. Lovex (Czech) powders here in Europe are the cheapest and are available, meanwhile I can't buy 5744 anymore - and its price (if available ) would be to high.
