Since the .475 Turnbull is around why not a .348 necked up to .475? Should be equal or better which means Bears to Elephants. Great caliber for the Winchester 71

Turnbull has two 475 cal cartridges based on 348 / 50-110 cases, the 470 and 475 Turnbull.

That might be too much fun!
Most experienced bear hunters, like Alaskan hunters and guides-know that the big bears and even some black bears require at least two shots.
So if your rifle has too much unnecessary recoil, a second or 3rd shot will cause a lack of on target accuracy: not good.
My 45-70s and two 450 Alaskans are right on the line as to controlled accuracy and proper feeding of cartridges for repeat shots.
You can find out the hard way, but not recommended.

Gary Reeder has a couple of .475's also. One on the based of the 348 and the other on the 45-70.
Spoke to Reeder and he said no problem to rebarrel to his .476 GNR which is the same but after receiving the rifle, it is in a lot better shape than the pictures on Gunbroker showed. I think I am going to keep this one as is and try to find a Browning to rechamber or just bite the bullet and get a Turnbull built .475 Turnbull
I’m getting to old to go hunting in Alaska anymore, I have 45-70, 325 wsm, 300 Jarrett, for the big bears, and moose, and I love my levers and have carried them throughout my life, but just got a 50 Beowulf in AR platform with Leopold Scot scope, it came with 300 to over 400 grain shells, gun can’t weigh over 6 pounds and shoots like a dream, big plus it’s semi auto in bear country and straight wall ammo. I know I’m not where I should be asking this but where else are there big gun guys hunting bears, sorry to high jack , but I thought it was interesting gun.

I agree that an AR platform shooting .45-.50 cal bullets at decent velocities seems to be a big-bear solution. It is a grotesque solution, due to my love for large caliber lever rifles of old...but to think you can shoot up to 11 rounds (.450 Bushmaster) as fast as you can pull the trigger...I dunno, that sounds pretty comforting to me in big-bear country. Sorry to hijack this great thread with ugly black rifle talk!
I agree that the AR style in .450 would be a good choice for bear protection especially if you put a 10” barrel and a pistol brace on the rear and a red dot sight. But it would be ugly as hell. It would be great for Salmon fishing as a utilitarian tool. But for my purposes I still consider looks and the Winchester 71 is the best looking factory lever gun to me.
Desert, that is simply bad ass.
I had nothing better to do right now.
