I've had a little experience with big kickers. I developed a technique with my 454 Casull that allows the force to be dissipated without getting hit in the head with the pistol. Of course that's an Encore pistol that is not really suitable for a conventional hold. With the Encore pistol, the 12" barrel, with no cylinder gap, develops significantly more recoil than a 10" revolver.
I was at the range shooting it and a guy with a 500 S&W was there at the same time, and we shot each other's pistols and compared notes. Both were about equally painful...
I taught my daughter to shoot the Casull, starting with a light load, then a medium load (equivalent to a 44 mag max load) to get the technique down and then went to a max load. Notice the right elbow is bent to allow the arm to flex at the elbow. She is pushing forward with the right hand and pulling back with the left, preloading the force applied by the right arm to keep the gun from flying straight back. This allows the upper arm to remain stationary while the forarm bends up with the recoil, allowing the gun to travel safely backwards and upwards.
