Use standard reloading procedures to work up to the following MAXIMUM loads using a 150 grain Nosler Ballistic Tip Bullet and standard Winchester Large Rifle primers in Winchester cases:
IMR3031: Starting load 36.0 grains. MAXIMUM LOAD 40.0 grains
IMR4895: Starting load 37.0 grains. MAXIMUM LOAD 41.5 grains
IMR4064 did not shoot too accurately in my rifle.
Both of these MAXIMUM loads are accurate. See which one your rifle "likes". My Model 99 in .300 Savage caliber liked the MAXIMUM load of IMR4895 consisting of 41.5 grains of IMR4895 which gave an average muzzle velocity of 2680 fps and consistently yielded 3/4 inch 3-shot groups at 100 yards.
Work up to the MAXIMUM LOAD with care, watching for high pressure signs.
Strength & Honor...
