I’ve built a number of 375/338s on that action for my customers & friends. They’ve taken a lot of Buffalo, moose grizzly & African plains game with them. One came home from Africa and called me ordering another one. The PH was so impressed when he shot a hippo end to end, he gave him the rifle.
375/338 would fit in between a 375 Whelen AI and a 375H&H AI, I’d think.
What barrel did you use? Stainless Steel?
I suppose I’ll never need one, BUT!!!
