It's not recoil sensitivity, its "shoulder mirage" caused from the heat waves from burning 70 grains of powder versus 20 grains!   

I never minded recoil in high power revolvers. I believe that some of the guys that shot automatics were the ones most likely to belllyache about the hard kickers. Figure it's because they shoot with a tighter grip to help the monkey motion of the auto's functions. The revolver responds well to a looser, absorbing method. Who, knows, I could be all wet here. But, I never saw action pistol guys doing as well in silhouette shooting nor vice versa. Bullseye shooter could go either way, I'd guess.

Back in the day when I thought I 10' tall and bullet proof, I did some work for a guy in exchange for one of Dick Casulls new hot rods, the 454.  We were shooting sillywetts at the time and it performed exceptional on the rams -and then some - it ruined bowling pins.    A shooter friend of mine happened to be a Dr. and when I went to him complaining about my wrist aching he slapped me up along side the head... Newton's third law applies - for every action there is a reaction.
I shoot this less and less it seems and when I have to, it's with loads that don't do it justice, just save a handful of Dick's loads back for when an image of my younger self feels they have something to prove.

Plenty of doctors think any contact with a gun must be associated with something bad. Plenty of other things that could shake a person up that they seem to ignore- motocross anybody?

What were they shooting?

I suppose that is why trap guns have almost no choke 

There was a guy taking pictures of a flintlock demonstration I gave.  He happened to catch fire in the pan.  My eyes were both wide open.  I always wondered if I blinked when the pan flashed. 

Various of my older friends have suffered detached retinas but were never target shooters or addicted to heavy recoiling guns.

So far as I know, detached retinas are generally result of weakened attachment of retina to underlying tissue. However, seems rational that any tendency toward loosening of retina can be helped along by heavy recoil or other adequate, suddenly applied physical force. 

At least two older persons I know had both retinas detach over only a few years. One had to be removed from his office by local acute medical personal when second retina extensively detached while he was sitting at his desk, leaving him totally without any useful vision.
