Another overlooked powder is Winchester 760 which is a slow burner, but with heavy bullets and a long OAL from a bolt action it might work great.
About LVR it don't burn any dirtier than CFE223 in my 30-30's. Don't think it will be any different in 223/5.56. Looks like charges will be a bit larger
with LVR after more study, it gets going at around 26 gr's and up, ww760 which I have used in 223 before and liked it, though compressed with a case full for AR's limited OAL
velocities were slower with 65GK's but that was with a OAL of 2.25. In my Bolt action I can take OAL up a good amt, 760 might be perfect.
Not for AR's.
