RE: Too much Kick?
So far the hardest kicking rifle I have shot is my 338 RUM. For me, it is getting close to what is comfortable off the bench with out any kind of recoil reducing rest or such. I will say that I opted to change out the HS Precisionhard rubber pad for a Sims. The HS pad did get to hurting a bit after about 10 rounds. The Sims pad did wondersto lessen that recoil and eleminateany pain.
Standing up off handit's not even close but on a bench I wouldn't want too much more.
I agree with SC, just because a person canpull the trigger for around or two from either the bench or off hand doesn't come close to meaning that they can actually handle the recoil of a particular cartridge/ rifle.
