47.0 grain of H4350 in R-P brass, WLR primer and a 160 grain Partition is THE load in my push feed Model 70 Featherweight 7X57. It shoots lights out and kills stuff cleanly.
I will use that same load (47.5gr) in my 275R for moose hunting this year. I did not have any luck whatsoever with 760 or IMR 4350 in this rifle and did not want to use the H4350 saving it for another rifle but in the end had to.
