I know this is a tricky question, but here goes anyway. Want to get started in long range shooting. I bought a Rem 700 in a 300 mag. Put a HS stock on it, and took the rifle to a gun smith to put a compensator on it, and lighten up the trigger. I topped it off with a Leupold 4-.5-14 with the BC lense. I would like to be able to shoot a buck out to 500 yds. Now the question is does all of this = a 500 yd rifle, and can this bee done with factory Federal 160gr NP ammo. If not what do I need to do to get there.
