i have a siamese mauser in .45-70. i dont think you will find recoil real unpleasant. i dont think it will be as bad as a 10 gauge, probably not as bad as a 12 gauge 3" load. a good hunting factory load is the PMC +P 350 grain. its advertised at 2025 fps muzzle velocity and 3167 foot pounds of energy. i started using them in a marlin guide gun and they work very well in my mauser. i like your rifle. i have a buddy in indiana that hunts with one in 500 smith and wesson. they can only use rifles chambered in pistol calibers there, or shotguns. if recoil is a ploblem try a slip on pad or fit a good pad to it. good hunting!
