I got into reloading a couple years back, so I'll be loading everything myself.
I'm going to get one or the other with the income tax; I still can't believe the wifey ain't yacking about it either. She must have just given up after 26 years of marriage, ha.
Thanks again for the input and advice; greatly appreciated.
Just think of it as a “fat" .308 Win'..., the cartridges neck, shoulder and length. It'll just push something like 190gr plus bullet faster & harder in an action that was build on a .308 Win scale.
The .300 WSM cartridges has “about” the same length of the .308 Win with a longer body but short neck.
