For my .300 Savage (in a Model 99 Savage) whitetail deer hunting load, I use the 150 grain Nosler Ballistic Tip, boat-tailed bullet in Winchester cartridge cases and standard Winchester primers. The load (41.5 grains of IMR4895) averages .75-inches (3/4 of an inch) firing 3-shot groups @ 100 yards off the bench rest yielding an average chronographed muzzle velocity of 2680 fps with a deviation of ± 19 fps (+9 fps/-10 fps) out of my 1953 EG Model 99's 24-inch barrel.
This load showed NO pressure signs in my rifle
even though it was listed as a maximum load in my reloading manual.
Since this is a "MAXIMUM LOAD", it may not be safe in your rifle. You should REDUCE this maximum load by 10% and use that amount of powder as your starting load and carefully "work up" to the maximum load for YOUR rifle.
My smallest 3-shot group using 41.5 grains of IMR4895 so far has been .1925 inches or just under 2/10th of an inch at 50 yards.
However, I did get a 3-shot group of .112 inches (just over 1/10th of an inch) at 50 yards using 41.1 grains of IMR4895 with a deviation of 13 fps (+6/-7 fps) giving a muzzle velocity of 2647 fps.
This load was the result of working up loads with four different powders (IMR3031, IMR4895, IMR4064 and Hodgdon's Varget), four different primers (Winchester, CCI, Federal and Remington) and three different bullets ((Hornady & Sierra 150 grain, soft-point bullets & the 150 grain Nosler Ballistic Tip, boat-tailed bullet).
