I shot some 15 yesterday under 120NBTs and it didn't quite compare to my Varget loads in MV or accuracy, but as you know, all rifles have their preferences.
Varget is a very, very good powder in a lot of cartridges; about the only thing there is to pick RL-15 over it is that '15 flows better & more consistently through a powder measure, IMO.
I would never feel shorted if Varget was the only powder I had in quite a few cartridges from the 223 to the 308.
