The 300 isn't loaded to particularly high pressures to start with (45 to 47 Kcup). If you back off about 5% or roughly 2 grains, you have a pretty soft load and very mild recoil. I personally would start with IMR3031 if I was going light in the .300 Savage along with a 150 grain bullet of choice. I tend toward the 150 grain PowerPoint or Hornady Spire.
