I went from the 308 W to the 358 BLR. Something I should have done twenty years ago.
Brass can always be had by reforming 308 Brass, and bullet selection is good for this cartridge
The 358 has a lot of thump but not to your shoulder.
I like it a lot better than the 45/70 guide
Bore that savage out or rebarrel, or price out a 358 W in a BLR.
Happy
