If your looking for an inexpensive rifle thats accurate and shoots the super cheap 7.62x39 cartridge check out the H&R line of single shots. In a good rifle the 7.62x39 is quite accurate I've made repeated accurate shots over 225yards.

I shoot a mini mauser in 7.62x39 and I love it, it's the gun thats inaccurate not the cartridge.

BTW-Wolf HP is still under 4.50 a box of 20. Doubt you'll find cheaper cartridges. With a good softpoint it'll double duty on deer as well.
