Re: worn out barrel
Well, you'd be doing good to get 1500 rounds out of any barrel chambered in .22-250 IMP, let alone 6k.
That caliber, pushing the 90 grain berger, in a 1-7 twist, would be something I'd love to see.
Even just a plain ole' 22-250, and that combo would likely extend barrel life to something a little more reasonable.
