[QUOTE="MontanaRifleman, post: 829078, member: 11717"] I thought I read in another thread that you had 1500 rounds through your STW. Maybe I was mistaken. In any case, to tell someone that they should expect to get 1500-2000 out of an overbore cartridge like an 7 STW is way over the top IMO. I don't know your gunsmith or what he said, so I am certainly not going to call him a liar. If he did say he was getting that kind of round count from a 7 STW, then I suspect he was running heavy bullets with mild loads of slow powder. I also have to wonder what accuracy level he considers a threshold for re-barreling. 1 MOA? 1 1/2MOA? This being a long range hunting site, most guys here are looking for 1/2 MOA or less accuracy from short to mid range and close to that to 1000 yds. Once your rifle starts shooting .75 MOA short to mid range, IMO it's time for a new barrel if you want to reliably hit a deer size target @ 1000 yds. Also, shooting overbore rifles hot is not a good idea if you care anything about barrel life. If you want to shoot your rifles hot, that's good for you. But I would never imply that will not have an effect on barrel life and accuracy. Besides, in long range hunting it's ALL about the cold bore shot. Heat and pressure eat rifle throats up. That's a fact. So, like I said, if anyone is going to assure someone else that they are going to "X" amount of rounds through a barrel, especially an overbore barrel, they should be willing to pay the costs if it doesn't happen.
