I am one of those guys who has a .220 swift and I love it. I had a guns and ammo that compared the .223wssm to the swift . they are really close to the same proformance when reloaded. But actually the .223 wssm had just alittle advantage on it. He was loading it all the way up to 4500fps and still shooting accurate. (if you are a speed freak) I really cant see that a 22-250,.220 swift or the .223wssm barrels (throat)will burn out faster then each other, they are all about the same I just like the swift it has been around for along time and is still doing what it did back in the 30's smoking some yote.
