I was just curious about members opinions of the 220 Swift caliber. I have a Ruger M77 Mark2 chambered in the 220 Swift. I originally wanted the 22-250 or 223, but the only caliber available at that time was the 220 Swift. The gun shoots nice. Beautiful gun with a nice big fat barrel. A lot of weight to the gun. I have read that the 220 Swift wears out the barrels fast. Any truth to that? If so, what should I be looking for and what steps should I take to minimize the wear?

The 22-250 got the good press from gun writers. The 220 Swift got the groundhogs!
The Swift is really no harder on barrels than any hot, small caliber IF you do not try to wing every possible FPS out of the cartridge. If you are a handloader, adjust OAL length to match YOUR rifle, and keep loads moderate (old saying- fastest load, most accurate load- pick ONE)
Have an old Savage I have used for groundhogs and prarie dogs for years. Closest thing to a Death Ray I own. Flat, accurate, modest recoil, devastating on small varmints.
Have a smith check the leade- front of chamber, rear of start of rifling, looking for erosion from gasses. If OK, should stay that way.
I've built .220 & .220 ackley improved and they're no harder on barrel throats than other cartridges with that level of velocity. As robo stated, heat is the main enemy to barrel throats. Any cartridge with that velocity will have very high throat temperatures. Space your shots out 5 minutes between shots, & keep the bore CLEAN & free of copper deposits, and it'll last you a LONG time. A lot of people believe their bore is clean when in fact it's still dirty with copper deposits.
Had a Ruger 220 swift also - bull barrel, trigger job, bi-pods, 4X18 redfield (I think that was the power) killed many a yote, cat, p dog wished I had it back. They are a great gun! Enjoy it. Sold mine due to losing all my good calling ground to the outfitters that moved in
