USMCvet69:
That load of 44 gr RL-15 with 165 grain bullet for 2614 fps is straight out of the Speer Manual #13. According to the manual it is within the 46 Kcup ceiling for the .300 Savage and was fired from a 99E with 20" Barrel.
In my opinion, that is too hot for the RL-15 in my cabinet. I would not exceed 42 grains. And in working up to it, I would start at 40 grains and use a chronograph. 2600fps for a 165 grain bullet is a lot to ask of the little .300 Sav., especially in a Savage 99.
42 grains is accurate in my 99 R. Velocity is right at 2500 fps from a 24" barrel. My bullet is the 165 gr Rem PSPCL. This is plenty for deer at 200yds.
Use caution and watch for pressure signs.
