.300 Savage, great cartridge.
You want a few secrets about it?
You can get or more accurately make .300 out of .308 brass, and if you’re selective can get cases that are much closer to chamber dimension by measuring and choosing by head diameter.
Secondly, you don’t need to crimp the bullets for a 99.
Thirdly, I ket my .300 go a while back and have a set of like new dies just sitting here if you’re interested.
