RE: .22-250 vs. .220 Swift
It is no small coincidence that the number of factory loadings for the .220 Swift has shrunk to only a couple,and that the .22-250 is so much more popular. Same situation with respect to the number of factoryrifles chambered for the two calibers -particularly when youconsider how much longer the Swift has been a legitimate factory caliber. I have owned and shot a Swift extensively - still have one in the cabinet that will cloverleaf Ballistic Tips. But when the barrel is shot out I will probably sell the dies.
Get the .22-250.
