About 30 years ago I decided my trusty and very accurate BSA 1917 Enfield 30.06 would be a lot better gun if I had it completely customized to suit me. And so I took it to a gun maker here in BC and left it with him for about a year and a half. New stock, jeweled the bolt, completely re-blued, pretty much the works. And he did a nice job of it. It was a one off, and all mine. Didn't shoot any better, but sure looked pretty!
I used it for the next season, handled it with kid gloves, a fretted the hell out of every single scratch and bruise it still acquired regardless.
The next year I picked up a Rem. 700 BDL Varmint Special 25.06 at a local gun show in Lloydminster. Weight didn't bother me, and could it ever shoot the lights out, including smallest group of my life, 1/8" at 100 yds.
The fancy custom rifle has been a Safe Queen ever since.
Point being: Unless you're after bragging rights, go for a gun you won't be reluctant to use and abuse. A great deal of the cost of a custom rifle is in the stock, select grade, and a helluva lot of work to finish it. But in the end, for all that money it's no less vulnerable or fragile than one off the shelf for $1000.
Cooper, for example, builds some supremely accurate rifles with synthetic stocks, as does Jerrett and others. Durable fiberglass/graphite/Kevlar stocks that are a big step up from most standard brands, properly fit and bedded. Use 'em for years, and...with reasonable care...not have it show at the end of the day. Forbes even goes so far as to serialize each stock to each action that it's fit to in order to maximize accuracy.
And considerably less money laid out up front!
Think long term before jumping. Custom rifles in beautifully crafted stocks can be like works of art...and that can be a problem.
FWIW.
