I am not sure how to gauge the "ouch" factor. However, I am pretty recoil shy. By that I mean that much recoil makes me less accurate. I am 6" and 185 lbs, and even my 270 will get to me at the shooting range, espeically when shooting Hornady 140 grain light magnum ammunition. What did I do about it? On my 270, I put a slip on recoil arrestor that is awesome for reduction of recoil ( a limb saver recoil pad). I got the slip on because it also fits my 7mm mag and my T/C Omega muzzleloader.
I also own a 338 win mag that really doesn' t seem to kick much, although I haven't shot it for long stretches at the range. I think it is because the gun is almost 10 lbs. A heavier gun definately helps with recoil.
I would recommend trying a limb saver pad. It will make a big difference.
