The last 700 I bought was a fluted, heavy barrel, .308, LR. It was OK, out of the box. Best load I could get was not quite a minute. I took it to my smith who blueprinted and trued the action and put it in a better stock with a cleaner float, and it vastly improved. Should have stopped there...
I probably put another $1,000+ in chopping the barrel and threading it, new timney trigger, bottom metal for mags, etc. I put an $800+or- Athlon scope on it. It would shoot a 20 shot group sub MOA, which is as good as any of my built rifles. This is the rub; it cost nearly as much as any of my built rifles cost to get it to function and shoot as good as I can shoot. If I has kept it I would have gotten a 6.5CM barrel for it.
I traded it to a gas-gun buddy (yes, there are one or two in the woodpile), who did not have a suitable bolt action rifle, for a Spike's AR with two .300BLK uppers. There's probably $3K in the rifle, and it's probably not worth $2K.
That was probably the last off-the-shelf rifle I ever buy. I just don't have the time or the money to be disappointed by or to improve a production rifle to where I want it to be. I feel like nothing is going to be what I want unless I have it built. I would honestly feel a lot more confident buying a used rifle with known components from a SH guy than I would a brand new one over the counter. The best situation would be someone who has a rifle with the barrel that's shot out that they're selling, and I can have it re-barreled. To me that's essentially like getting a new rifle. I always feel like I'm shooting a new rifle when I re-barrel!
