I have a 300WSM and the recoil is not that bad, I went to the range and put 20 shells through it and did not bother me.

Is it too much gun for 50 to 150 yard shots, no I don't think so. It is all in what you are comfortable with. As others have mentioned the 270 and 308 are also good choices, but I love my 300WSM. I will find out how the deer like it in another week.
