The .300 Savage was introduced around 1920 in the Model 99 lever-action rifle, and would become the most popular caliber offered for that classic. In developing the new cartridge, Savage wanted to push a 150-grain bullet close to 2,700 fps, but real velocities ended up around 2,630 fps (depending on barrel length). Regardless, in 1920 this was outstanding performance from a short-action cartridge that was clearly ahead of its time. In addition to the lever-action Savage Model 99, the .300 Savage has been offered in a variety of pump, autoloader and bolt-action rifles. Ammunition is still offered by Federal, Winchester and Remington, and due to the large number of guns still in use by hunters, sales remain steady.
A standard full length sizing die will generally size cases sufficiently to allow easy chambering of loaded cartridges, however, some rifles (including lever actions, pumps and autoloaders) will require cases to be sized in a small base sizer die to allow reliable chambering and function. It is suggested to size a few cases, then chamber them in your rifle to determine if they chamber easily and that the action closes with normal effort. If they do not, then a small base sizer die will likely be required. If dies have not already been purchased, a small base die set is probably the best choice to begin with.
Today’s factory loads are generally advertised to push a 150-grain bullet to 2,630 fps, or a 180 to 2,350 fps. Several powders duplicated (even exceeded) those ballistics with Hornady bullets. In regard to producing top velocities and accuracy, a few outstanding powders included IMR-3031 (with 150-grain bullets), IMR-4064, IMR-4320, Hodgdon H-4895 and Alliant Reloder 15.
None of the accompanying loads exceed current industry maximum average pressure limits of 46,000 CUP.
