When you say Swift, you've said it all. I have two. One is a heavy S/S barrel with a 6-24 scope. It was my first and has been a good one. I carried it on the only two PD shoots I have been on. When the guns we had would not reach that far away Praire dog, we would unleash the Swift. It accounts for my farthest one shot hit on a coyote. 597 yards. It has an estimated 1500 rounds through it and viewed under a borescope, the first 1/4 inch of riflings is washed out. I got tired of lugging that heavy thing around for coyotes and last year picked up a Swift in Rem 700 Classic. I hope to never be without a Swift.
Will it burn out a barrel. Yes, but no more so than any other cartridge sending that much powder down that small of hole. Will it out shoot any other factory produced cartridge? Yes. It can be downloaded and save some barrel life, but why? The purpose from its inception was for speed.
