52 grains of 760/H414 will get you 2900fps+ in a 22 inch barrel.

Lots of luck. In my Winchester M70 Featherweight, 49.0 gr. of W760 was showing pressure signs and I had to go all the way back to 47.0 grains before all signs of high pressure disappreared In my custom FN Mauser that load (47.0 gr.)would lock up the bolt nice and tight. However, that rifle does have a minimum chamber. Final velocity in the M70 was 2800 FPS. Bullet was the 140 gr. Nosler Ballisitic Tip.
