RE: Too much Kick?
You darn right there are guns that kick too hard. I purchased a Mossberg 835 ultra mag several years back. It shot 3.5" 12 gauage shells and had a superlight synthetic stock. I shot that dude and it would cross my eyes. I even shot it with 2.75" trap loads and didn't like it. That shotgun got traded at a gun show.
I once shot a 450 #2 double rifle. It's my dads and its a old rifle with two triggers, one for the right barrel one for the left. I made the mistake of pulling the front trigger first, when the recoil hit me I squeezed the back trigger. Double whammy!!! It shook me bad. I realized what had happened and it took some nerve to try it again, this time back trigger first. It was still pretty mean. I've never shot it again. Though I'm not scared of it.
When shooting my 338 wm off the bench it can get to me. After about 5 shots I start to get jumpy. To combat this I use a shoulder pad when target shooting.
