yep, IMR 4350 at 54 to 55 gr has been fantastic for me in my pre 64 '06. Its also what convinced me that Ken Waters knew what he was doing with his Pet Loads articles. I fooled around with various combinations with marginal luck. Then found Ken's article on the 30-06 (his first update) and tried this load first. I've rarely tried anything else since. I load 180 Speer Hot Core, Nosler Solid Base, or Rem Cor Loks for practice and Nosler Partitions for hunting. Works like a charm. I have had good luck with IMR 4831 too but don't recall the charge weight and mostly save that powder for my 300 win mag.. Oh, I generally use CCI standard rifle primers and RP brass.
I've tried AA3100 with ok results.
