I ordered a bunch of it earlier this year hoping find some good loads for it. I haven't been able to test it as much as I'd like but so far nothing spectacular in the one AR I've tried it in. I've found some loads that beat American Eagle 5.56 bulk ammo, but nothing near as accurate as ANY of my Varget .223 loads. Varget and Benchmark have produced MY best .223 loads. I wish ADI/Hodgdon would produced a short cut version of Varget.
I have had pretty good success with CFE223 in .30-06. Good accurate hunting loads, but nothing I would consider match grade. I'm not giving up on it yet for .223 but I probably won't be testing it further March or April.
