Honestly, these days, standards on rifles are so high, it's difficult to go wrong. I would go to a pawn shop, look for a Savage, Winchester, or Remington 22-250 with a varmint barrel, and give it a try. My dad bought a like-new Remington 700 VSSF 22-250 from a pawn shop, and it shoots about 3/4 MOA with WWB 45 gr ammo. If it needs some tightening up. size your handloads, have the trigger lightened. If it still isn't sub-moa, then I would look at bedding and re-barreling or truing the action. But like I say, these days it's so competitive, no one dares release a varmint rifle that isn't sub-moa.
