Was the Swift a wildcat or original case design? For some reason I thought it was an '06 wildcat like the .270 and 25-06. Then I saw one, actually the fella gave me the round. He is getting out of his hobby of extreme long range shooting and PD hunting. The 220 round was next to his desk with a bunch of other unusual rounds....I snagged the 220 and asked him what was up with it. He said it was the 220 Swift Improved. You could tell it was an improved. He said 4700fps.
