I've shot hot loads in my 45 Blackhawk, plus full power 44 magnums, and though they are quite tolerable, I can't imagine anyone wanting to shoot something with more recoil!
You may get away with that kind of wrist impact for a while, but I suspect it will do you permanent damage over the long haul, if not sooner!
Remember that soft white squishy stuff between your bones? Believe me, it will fracture and tear with that kind of abuse, and no one can accurately predict just how much your joints can take!
Please be careful, and don't use those big bore, full power, bone crushing loads, for practice or plinking. It may be fun now, but years from now, you could pay a very high price for the kicks of recoil!
