Now, I knew the bore was not in the best shape as it's kinda dark. I stopped at the counter on my way out and was BSing with one of the guys on staff at the range. Turns out he was the gunsmith for the range and for a few bucks for bench time, he offered to stick a bore scope down it and let me see whats what. Dark isn't the half of it. There is some pretty decent pitting and scoring. She's lead a hard life. The smith offered to run a couple gauges in but told me that the barrel was just about done. He said they could rebarrel it and spiff it up if I wanted, went into the spiel on it. I thanked him for his time and left. So here I am on the internets looking for your expert opinion. First off, this rifle is not original. It had its original stock cut and shaved down and sporterized. Bubba already dun his damage long before I was born. The way I see it, I have a nice captured German action and bolt that is asking me for a new barrel and a nice modern stock and optics. I'd like to use the existing bolt which means keeping the 12mm Mauser rim diameter. So what cartridge do you think would be a good fit? I immediately thought of 6.5 Creedmoor, but there's a whole wild world of .260 Remington, .280 Remington, .270 Winchester, 6.5x57 mauser. 7mm Mauser. I don't presently handload so assume factory ammo. If you had a war surplus German Mauser K98K action (by way of Yugoslavia) in good condition, what barrel would you stick on? And is it worth buying some reloading equipment?
