I have a .300 savage with a 4 power scope, and for whatever reason it seems much more comfortable to shoot than my iron sighted marlin 30-30, and feels much more comfortable than my .308. Here and elsewhere I have read that 40-41 grains of IMR4895 with 150 grain bullets is a very accurate load for these rifles, but I have yet to try it. I have, however, had initially good results with 42 grains of W748, which is a max load in some reloading manuals. A note of caution, though sierra's max loads are typically light compared to other manuals, their loads for the .300 savage are VERY HOT. Definitely back Sierra loads for this cartridge WAY down to start with.
