IMR 4350 and the 30-06 are made for each other. If you cannot get accuracy and performance out of this combo then you have rifle problems.
I think this is probably right! I burned a truckload of the stuff in the 30/06 with 150-165 gr bullets and was care free for years. It always worked great.
But I later discovered that IMR 4350 is one of the Kings of temperature variation;fully as bad as RL22 in some cartridges,which gets a lot of flack for temp swings. Has it gotten better recently? I don't know....
But I still use RL22.....and IMR 4350 in some applications. Mostly though I have switched to H4350 in the 30/06.
