To be frank, I suspect that any load in a .300 Savage using a 150 grain bullet that HONESTLY yields 2750 fps is very likely "pushing" or EXCEEDING the limits of safety due to high pressure.
I've been reloading for over 40 years. A few years ago, I worked up a MAXIMUM LISTED LOAD as my hunting load for my 1953 late model EG (Savage Model 99) with a 24-inch barrel using 4 different powders (IMR3031, IMR4064, IMR4895 & Hodgdon's Varget), 4 different standard primers (CCI, Winchester-Western, Remington and Federal) and 3 different 150 grain bullets (Sierra, Hornady and Nosler).
My final load was/is a Nosler 150 grain Ballistic Tip bullet in front of 41.5 grains (a MAXIMUM load) of IMR4895 sparked by a Winchester standard large rifle primer in once fired (and "accurized") Winchester cartridge cases.
This load averaged a muzzle velocity of 2680 fps on an 85º day and yielded ¾ inch, 3-shot groups @ 100 yards off a solid bench rest. This same load averaged 2664 fps on a 70º day. No load yielded a higher muzzle velocity with any combination of any of the components.
I noted that what my reloading manual called a "maximum load" didn't show EXTREME pressure signs, but did show SOME high pressure signs such as somewhat flattened primers. Due to these pressure signs, I feel the listed loads, while safe, WERE "maximum loads".
The SAAMI average pressure for the .300 Savage is 46,000 CUP. Before I'd shoot the load listed in your original post which yielded 2750 fps with a 150 grain Nosler Ballistic Tip bullet, I'd like to see what kind of chamber pressures that load was registering.
Strength & Honor...
