I'm 33 and I use my 243 almost exclusively. I think you hunt with what you are comfortable with. I don't like heavy recoil. I am very susceptible to flinching and I have killed nearly all my rifle deer with my 243. The gun is (a model 70 btw) unbelievably accurate too. I shot a doe at 260 yds, and honestly, I didn't hold high whatsoever and she went down where she stood. 100 gr federal round. A lot of folks are realizing that they don't need the power of the heavier hitters, altho I do hunt with them from time to time. They are both good calibers.
