Just read a review of the .500 mag. They said it kicks harder than a 44 Mag, but not as harsh as a .454 or .475
I guess 4 1/2 lbs empty, 5 lbs full soaks up recoil pretty well. What really blew my mind is that there is apparently plenty of case room left with current loads. They say there's enough case room to load/shoot 500 gr bullets!
