For a new shooter desiring to shoot to 1000 yards on game I usually recommend a 300 Win Mag. Get a good rifle from a reputable gunsmith (setup for Federal Gold Medal Match 190 load). Buy a set of heavy duty rings and bases, install a good scope and buy 1000 rounds (single LOT number) of factory Federal Gold Medal Match (GMM) 190's. IMHO you now have an accurate and capable rifle that is designed to shoot factory ammo. You can reload for it if you wish or you can shoot the Federal GMM. I shoot/hunt tactical (sniper) style, bipod and sandsock, first round hit scenario...
If the 300 Win Mag GMM ammo is not to your liking you can sell it for your cost quite easily (assuming you buy it at a good price (www.ammoman.com
or the like).
When you go for your second or subsequent rifle (post 300 WM) you can sell the 300 WM or rebarrel/chamber it but you've had the opportunity to learn on a rifle shooting known accurate ammo with a minimum of tinkering. (Less tinkering means more shooting and more (good style/proper technique) shooting shoot equate to a better shooter.)
