FN AR or a AR-10. IMO there is no sense in slowing down to reload, unless you can actually out shoot a sub-MOA rifle. Saw a few Remington 700s on Google shopping under $600. Midwest hunters seem to always have a great price if you know a dealer. You also might want to consider some of the classics like a Mauser, Mosin Nagant or Lee Enfeild? If you get a C&R license you can order them off the INTERNET. You might also want to research a particular caliber like a .300 Mag, just something that has a particularly flat and fast trajectory.
