If you want cheap, Norinco Bushmaster 7.62x39. Cheap as chips ammo, usual barrel twist is relatively fast in the scheme of things so can be used for relatively heavy subs and did I mention cheap? These things can be had set up with a decent scope for under a grand, and if you look around can be had second hand with a decent low mag scope for under half that. Will probably need a bit of a polish around the action as finishing is usually rubbish to finished by foot, and likely a bedding job but once that's done they are pretty good.
Mine holds about 1" to 1.5" at 100m after all is done, and is perfectly acceptable for deer out to 150m which as noted above is a LONG shot for your average bush rifle.
