BSA martini 12, 15, or 12/15's are easily the most accurate target rifles under $600. Hard to come by but worth way more than they cost. Islandguy is a member of my club and I watched his BSA 12/15 put 10 shots in the x ring last week. The group couldn't have been much over .4" at 50m. Not bad for a sub $600 gun with open sights using federal 510 bulk ammo.
