The .348 was the premier brush-busting NA big game gun for a quarter-century. My dad took bear and boar with it, and it'll do for whitetail as well. The recoil is not unmanageable if you practice with it. .308 is a bit underpowered for dangerous game. And any boar hog is dangerous game . . . I am quite familiar with them because they infest my parents' island in coastal GA. They usually run, but the occasional big boar will stand his ground. A number of folks on the island have had dogs killed - big dogs, not yappers. I do not walk out on the island in the dusk without my .41 Mag . . . just in case. (I don't have a .44 Mag because that's my definition of a "useless cannon". I put a couple of cylinders full through a friend's S&W, the cylinder release came loose and cut a nasty gash in my thumb.)
And I'd like a .375 just because . . . mom and dad were planning to hunt Kodiak bear in Alaska - dad bought the .348 for mom, and he was shopping for a .375 when mom turned up pregnant with me. Every so often he looks at me with a wistful sigh and asks, "Why couldn't you wait until I'd bought the .375?" Neither the .348 nor a 7mm Rem Mag with full house loads bothers me particularly, and I can always download the .375 . . . (can't own a firearm without owning the dies, right?)
