22-250- because of Rick Jamison's many glowing articles back in the 80's touting it's high velocity, accuracy and varmint vaporizing capabilities. Ironically, I never purchased a 22-250. I instead became a huge 220 Swift fanboy after purchasing one in 1992 when Remington offered it in their Classic line. Now have 2 of them and will probably never own a 22-250. The Swift just works so well. smile
