Some great advice on here so far. As a first and "do it all rifle", I'd aim toward well proven cartridges--I love the 7mm-08 for North America and Africa Plains game. Low muzzle blast, mild recoil but a serious game harvester. I have 16 rifles and shoot that cartridge the most--recently had Fierce Firearms build me a custom. I reload and shoot a Barnes 145 gr LRX @ 2844 FPS from a 22"Bbl. That said you'd also be well served with a .308 Winchester and if you want little more jack you are never wrong with the venerable old tried and true 30-06. A one gun guy could find a nice 30-06 in Ruger, Mossberg, Browning X-Bolt, Tikka, Rem 700 etc., and call it a day. Any of these cartridges will do what you need and you can find a wide selection of ammo anywhere. A lot of good rifles out there, my favorite off the shelf by far is SAKO 85 but that is gonna be over your budget ($1800.00 or so). I also love the Viper Vortex 4-16X44 HS-T scope with drop in turrets from Kenton industries. A little more $$ and you can get the Razor. Very good scopes, lifetime warranty and bang for your buck. It'll let you dial if you like for long range or use the CDS hash marks or just zero at 200 and put the "thing on the thing" to 300 yds. Weight is only 19 oz. That said, you are never wrong glass wise with a good, solid Leopold. Tho I love the cartridge, I'd shy away from the very hyped 6.5 Creedmoor as a first/"do it all rifle"...great round for whitetail deer or close work on Elk, accurate, fun to shoot, but my experience over several years and three different rifles is it just doesn't have enough huevos (IMO) to get 'er done over a broad range of use unless you are an experienced shooter.
