If your wanting a rifle for under $300 that will do nearly everything I suggest looking for used Savage bolt-action rifles. I have spotted some used for as little as $250 in like-new condition. Chambered in any moderate cartridge (.270, 30-06, 280, 7-08, .308, etc) it should be good for everything from small game through moose-size critters. Handloading of course makes any one of these cartridge choices very versatile. Savage rifles also are quite safe, reliable, and accurate. They may not be pretty, but they get the job done.
