Right on buddy, welcome to the club! You may wish to look at the following rifles:
Norinco M14 .308 Win also eats 7.62mm Nato, not too expensive and lots of mod options, great for hunting, targets, pretty much anything
CZ with the longer barrel is non-restricted and looks like lots of fun, if you buy milsurp ammo its pretty cheap for a crate or 2, you can also get commercial hunting ammo for 7.62 soviet as well
There's also the AR180b, a bit pricey but its 5.56mm and mag fed
SKS is also a nice option if you like 7.62mm Soviet calibre, rifles are really cheap and you can mod them to the hilt, ammo is cheap, won't break the bank at all for your first shooting iron, buy 3 of them just in case!
Remigton 7400 is a semi-auto hunting rifle which comes in various calibres, you can check that out too
Ruger mini 14, .223 rem, can also mod the crap out of it, popular rifle
Whatever you choose have fun and shoot safe, good luck with your choice, I am sure you will get lots of advice here.
