As a factory chambering, the .220 was pretty much dead.
Then about 1976 Ruger resurrected the round with a limited run of Model 77's. It was successful enough that it became a standard choice in the 77 and the Number 1 rifles. Other manufacturers may have chambered it as well but I'm not certain. I seem to recall a guy with a Savage rifle at my club. Single-shot and I believe it was a Swift.
Now the round seems to have fizzled out again despite a dedicated fan club.
Why so little love for this cartridge now?
My Ruger 77 in .220 Swift was an excellent rifle and a 'chuck killing machine.
