There are loads of suitable rifles available at most pawn shops and in the used rack at your local gun store. Hunting season is over so there are some pretty good bargains to be had. Any decent bolt action should do the trick. If cost is an object look for one with some finish wear. As long as it is mechanically sound with a good bore it should do the job. I recently bought an almost new 1980 vintage Remington 700 in 22-250 with a 3x9 Refield scope for $450 from a local pawn shop. I also bought a late 60s Remington 700 in 7mm mag with a 1x4 Redfield scope for $275 awhile back from a different pawn shop. It had some finish issues but once I refinished the stock it looked good and shot well. There were a lot of rifles to choose from. Don't forget to negotiate. They do drop their prices.
