Hi Neil ,
Thanks for cartridge date on MH and other weapons. Would you perhaps know the FPS of the MH 480grn bullet say at 150m. It' sfall, or trajectory path at that range would also give some idea of its shooting ability. I suppose firing a MH singlehandely ( a la pistol mode) would be much like firing, pistol mode, a cut down 12gg shotgun, with a 450 grn slug in front of a magnum loading.

Barry initial Muzzle velocity is approx 1320 feet per second (about 400m) with de -acceleration beginning almost immediately, in foot / pounds energy this equates to approx 1920lbs
In other words the poundage on yer shoulder (recoil energy) is roughly calculated at 38lbs (rifle) and 40 lbs (Carbine), firing the rifle single handed would mean the chances of hitting anything remote, and the whole thing would be like a bucking bronco, its not something I have tried!.
To illustrate the de-acceleratiom, at a target on the ground at 500 yards, fired from prone, the bullets trajectory would reach an apogee of 8ft (2.4m) before decending.
