I have used Varget for 223 and 308. It works really well but it is a stick powder so it does make a "crunching" sound every so often. I really like that powder, but it is extinct around here. I used it to load Hornady 55 gr vmax in 223 and Nosler 165 gr Ballistic tip in my son's 308. I try to stay middle of the road when I load. I never load up to the max. I figure my son might be shooting it in the future so I do not load up to the max. I would rather be safe than sorry. I have been reading up on CFE223 and if you can find it, buy it! It will work in over 20 calibers plus it will clean copper residue out of a dirty barrel. This info is according to the 2013 Hodgdon reloading manual.
