While I haven't run any top level loads out of my 500 JRH BFR yet, I have found the recoil to be surprisingly manageable. Substantial but not sharp or hard to control.

Per my calibrated palm recoil-o-meter 440gr bullets @ ~1175fps feel like 2-3x the recoil pulse of a top end 44 mag load but more of a push than a violent jerk. You definitely need to hang on but the bisley grip distributes the recoil very well.

I'm sure that a case full of H110 @ 1400fps will be more attention grabbing the JRH does not need to be run that hot to hit very hard.
