As to valuation, $800 is probably about right. Used to be $500-$600 as BSA said, but those days are gone. Standard chambering classic stainless are now routinely bringing over a grand.
That. I've had M70 Classics in nearly all chamberings, but not a single WSM graces my safe.. There have been feeding issues, chamber issues and reloading issues with WSMs. Yes - all of them can, but the WSMs seem to rule that roost....(in my experience over the last 20+ years)..
Part of the reason I said they had their issues. Especially the 7 digits. A guy just has to be mindful of that. We've heard of some of them having "oval" chambers and scope mount holes not drilled on the center axis, really bad bedding (which is an easy fix). You could name more things to watch out for, since you worked on tons of them over the years. Would it keep me from buying something like what the op is asking about? Maybe. The thing is when you are looking a rifle over, new or used, there are things you look for. I check them out thoroughly and sometimes even bring a buddy along that is just as versed in buying used rifles. They may see something you don't. There should always be a check list of things you look for when looking at a used rifle. And I'd consider this one a "used" rifle, even though it is described as "NIB". Is $800 a good deal. Probably, but it's not a "money maker" per se. I know a lot of these guys aren't out there buying rifles like some of us, so they stumble across an average deal and buy it with the assertion they are never going to get rid of it. I've heard that 100 times here. I, on the other hand, treat them like they are my savings account or like I remember you saying a time or 2, your "401K". I've even ran across some rifles that, now I wished I would have bought. Last fall, right before elk season a buddy and I were in Cabela's and I spotted an Extreme weather. Dang thing was like new. I looked at the price tag and it was $625.00. I was like wth?? Then I saw it was a 325WSM. That explains it. However, if it had been a standard cartridge it may have been more money. A buddy and I were at the coast, last summer, near where he lives and we stopped in at the LGS there and just for chits and giggles we go and look at the guns. They had a 308W Extreme weather. It had dust on it, it had been there for so long. It was marked clearance: $800.00. I looked at the serial number and it was a 2009 rifle. The same fn, literally, rifle we had looked at 10 years prior. No one likes 308w over there I guess. A lot of guys using 300 RUM's and other magnums in that area. The guy behind the counter said the rifle had been there for at least 10 years that he knew of. They just wanted to move it down the road, so they marked it way down. Like I said before, you just got to get out and see what's out there. The 300WBY XTR in the Mcmillan we were discussing in another thread is only $800.00. That would be a hell of a deal for someone. Yeah, it may need a new barrel, but that's an easy job for someone like you Lee. I've since seen 2 mcmillan winchester winlite stocks on ebay sell for upwards of $500.00.
