I have a son that is very recoil shy. He does not like shooting even his 30-30 or the 300 blackout I built for him. Had to load some 125 grain mouse fart loads for him to shoot the 30-30 more than a few times at a setting or shoot subsonic loads in the 300 blackout. But he will shoot 230 grain hardball loads going 850 fps out of my Kimber all day long. I think it has more to do with setting and shooting the rifles and standing and shooting the 1911 more than anything. He also loves shooting my Ruger Blackhawk 45 Long Colt with 255 gr Cowboy loads going 850 fps. The Ruger shoots much softer with the cowboy loads than the 1911 does going the same fps and I did start him on that.
