RE: What 22-250 is good and affordable?
Either the rem 700 bdl varminter or the Ruger 77 Varmint rifle. I own the remington, and it is a great gun. Affordable and great accuracy. The ruger is even better in my opinion except for one major flaw. As is common with Rugers, the trigger pull is very stiff.
If you are willing to have a new trigger put into the Ruger (about $80), that would be my choice. Both rifles are in the mid $400s.
Good luck.
