I am looking for advice on a rifle for my sons first big game gun. My son is 10 years old he can handle full power 30-06 loads. So my question is what caliber would you get if you was me buying him his first big game rifle? I reload so I can lesson the power if its something bigger than a 30-06. I want something that when he gets bigger that he will not be scared of. Where I'm from we hunt antelope mule deer and elk. Thanks.
