.458 Win Mag and H335 Powder

Anyone have any experience with this combo and 500 grain bullets? I have the reloading manual data suggesting between 75 and 77 grains as max load. I was curious if anyone has done some 'speriment'in with this combo and what seemed to work best.

I had the same question just 3wks ago. I chrono'd 77gr of H335 pushing a 500gr Hornady out of a M70 Classic, 22in bbl. Six round avg of 2110fps. Easy extraction with no signs of excessive pressure. Bob
