It is going to kick. A lot. Even if it goes 11 pounds, which it won't, it is more for looking at and speculating than shooting.
I have this very rifle and find it no worse to shoot than my 458 Win Mag CZ 550 with 500gr loads.
The barrel is noticeably trimmer than the 458 and 416 Tropical's, closer to the 375 but with a bigger hole. Mine balances perfectly with iron sights.
