My father won a sako 338 federal at an auction. He was exited at first because he thought it was a 338 win mag. He was so discusted when he found out it was a 338 federal and looked at the ballistics he hasen't shot it yet and it has sat in the gun rack untouched for at least a year if not more now. He is looking at rebarreling it to a 243.

The ballistics to me say "meh" so what. If all your shots are limited to 200 yards and you feel the need for a large hole using a bullet with poor SD then this is probabbly a good choice, but then again there are a number of other good choices out there that already do just that.

Not that it is a bad caliber, I just don't see what it has over other calibers.

Now in an Ar10 it makes perfect sense and almost seems made for an auto.
