H4831 was the go to powder for years. I4350 works very well also. I prefer it with 150,165 and 180s. I would shoot that during this shortage. I have shot a lot of bucks in Pa. with my old 300 Win. I often shot 150s or 165s because the longest shot I would get was 500, but up to that point there was no dialing just shoot. At 500 hold over was required. Enjoy great caliber.
