Re: Fast twist 22-250...barrel life?
It's not the fast twist that shortens barrel life, per se. but the heavy bullets we use with them. High pressures will (of course) exacerbate this, but I'd expect to see substantially better barrel life out of extremely high velocity loads with light weight bullets than I would with somewhat lower pressure loads using heavy bullets. Still, it just comes down to what you want to do with the gun. High velocity over moderate distances is fine, but when the range stretches out a bit, nothing beats the advantages of a high BC bullet, and that means added weight.
You want toplay, you gotta pay. Barrel life is often the price we pay for such games.
