bigcountry, shooting .5 MOA at 100 yards is a lot easier than shooting .5 MOA at 200 yards. I don't doubt his rifle has fired .5 MOA at 200 yards, it's the "all day long" that I don't believe. I've shot benchrest rifles for years and conditions have to be almost perfect to shoot those outstanding groups at longer ranges.

I've owned benchrest rifles that were 1/4 MOA and under rifles at 100 yards, but it's not that easy to get those 1/4 MOA at 200, 300, etc.

I wouldn't touch a used heavy barrel with a ten foot pole. Knowing he's had a lot of work done to a rifle just tells me he's probably a serious shooter who's put thousands of rounds through it. 2000 rounds won't kill you as far as the average hunter, but the top accuracy of the rifle is probably long gone.
