I too have a 348 Win, I think it's a Win Model '73, it's rather rusty, so have never fired it or even bought ammo for it! The bore looks as rough as the Bearing Straits.Cape Buffalo with 50 Alaskan, 348 Winchester, 35 Remington and Whelen for moose and mountain goat, 7MM TCU on mule deer, caribou with 8MM Remington mag.
That's not hard to believe, I own a .41 Magnum; so I've seen it first hand.Believe it or not, there are still people that have never heard of a .41 Magnum. I've been hunting with a Ruger NMB with a 6.5 inch barrel for over 30 years with some success. And still get asked, "a 41 what???"
