I haven't read that article but I did read a post on this forum where the poster blamed his elbow bursitis or arthritis (there goes my memory) on shooting hot magnums. I hadn't considered that before.
It also likely depends on how frequenty we shoot the heavy recoil loadings - aside from how strong each impulse is. I know I personally don't shoot magnums frequently enough to cause a problem - I don't load 357 yet and buying them would be too expensive for me.
Lately I've been more cautious with my hearing too and I always double up. I'd imagine high volume of magnums would over time have a more detrimental effect on hearing.
