The hardest to control gun I ever shot was a german Weatherby Mark five in .378 with lighter 24" barrel. with factory loads it jumped to 11 o clock fast!!!!

I also owned a Savage single barrel 10 ga. I used turkey hunting. I took the 2 lbs of steel out of the butt to make it easier to carry. Gun had a 36" barrel , but with 2 1/2 oz handloads would still raise the muzzle a lot and bury the hammer in the web of my hand!!!!!!!
