i know that this carliber is real popular. but it gets on my nerves people use it on deer and elk where i think it's only good for groundhogs. yea it'll kill about anything but so will a 22 lr. as a deer gun it works best on boardside lung shots. don't hit the shoulder or you'll be chasing for a long time. lest face it it's a gun for the expert who can thread the needle with the prefect shot no margin for error for around the edges. and no you don't need a magnum either. a .308 class gun will give you all the power you need as still be easy on the shooter to boot.
