With my Mauser 404 I did shoot a couple of red deer and some feral goats with the RWS 347gr bullets I show in my earlier post. They are very accurate bullets in the 404 (has the original 10.75x68 barrel) and I only load them to about the same 2200fps velocity as I do the RWS 400gr solids I have used on buffalo.
Unfortunately I didn't recover any of the 347gr bullets but they certainly dropped the deer and goats in their tracks.

Donald Anderson, son of Kenneth Anderson the Anglo/Indian hunter who 'specialized' in dispatching man-eating tigers and leopards in Southern India earlier last century, was a great exponent of the Mauser 10.75x68. Some say Donald actually dispatched many more man-eaters, non man-eaters and elephant with his Mauser than his famous father did with his Win'95 lever action in 405Win that he preferred.
