Savage Axis, Any number of Remington model 7--'s, 783's, 770's, I've seen NEW 700 ADL's at Wallyworld for under $300 i think., Rossi makes some decent single shots, H&R makes really nice single shots, well they used to, you'll only find used ones now. Marlin lever guns, possibly some of the newer bolt actions that people traded in. Most of those are going to be used, you can get the Axis New like I did for around $275 without a scope, I got mine for $270 out the door. The 783/770 Remingtons you could probably get for under $300 new. Without a scope though, or if it comes with a scope, it will be very budget end. You can get a really nice M24/47 or M48 Yugoslavian Mauser for less than $300. With Irons Sights I can hold a bit less than 2.5 inches at 100 yards, and I've killed a deer with mine recently, mine is an M24/47. Any number of C&R guns would be perfect if a scope isn't required. Mosins, Mausers, K-31's or any of the Swiss variety of straight pulls would be perfect and are super accurate.
