You'll see the difference between a 22/250 and a 220 swift using a chronograph no doubt . But in the real world of shooting there is no difference. If your shooting at tin cans at 300 yds the 220 swift will provide no significant advantage over the 22/250. Both have to be spot on with range estimation along with wind and angle your shooting. I once had to have a swift and then a AI 22/250 . Now I have a standard 22/250 and I can blow up water filled cans at 300+ yds just fine. Beware varmints and predators. My standard 22/250 get the job done just fine.
