i have been using and loading for a 300 sav. sense i was a boy. the best powder i have ever used is varget with imr4064 on it's heals. a wile back i bought a can of levereverlotion or what ever you call it? i don't care for it, its to snappy and the accuracy did not impress me. if you were close by i would give it to you. the varget in my 48 years of handloading experience is the best rifle powder to come along in my lifetime.
