Yes, I can see how a custom stock contributes to a custom rifle, but I think that there are other variables that I would think of before I think of a particular stock.
For example, most people would agree that the best, if not one of the best, true synthetic stocks are the one made by McMillan and HS Precision (and probably in that order). Granted, these company's can offer certain types of stocks with certain types of dimensions, but I look into other factors first, such as the following: barrel, action, trigger, and bedding.
The thing about true customs guns is that they can be quite expensive (but, then again, "expensive" is a relative term - to me $1,000 might be expensive, for Donald Trump, $1,000 may be chewing gum money.)
For me, the most important end result is accuracy, which is closely tied to quality for second. Granted, you can get a Savage rifle which will cost about $400 and shoot sub-inch groups all day, and get a custom rifle that will cost $2,000, $3,000, or more, and shoot with the same accuracy. However, the quality of the custom gun (components, feel, fit, and finish) are incomprable to a Savage.
The question then boils down to this: Is a custom gun really worth all that money?
Well, ask 10 different people and you will probably get 10 different answers. If everyone said "no," then how would you explain all of the different custom gun makers staying in business?
I may get a true custom gun one day, not necessarily because it is of high quality, or because it shoots great, but because it was custom built just for me. That's not to say that I am arrogant or want to be different, just that there seems to be some pride in having a gun made just for you.
In the meantime, I have my Remchesters customized by having mostly trigger jobs with the pull set at 3 lbs. Other than that, I sometimes have the barrels recrowned. In most cases, just this alone will allow my guns to shoot sub-inch with most factory ammo all day - and that's with the junk plastic stocks that the Remchesters come with.
Of course I like the Tikkas much more because, in my opinion, their fit and finish is excellent, their triggers are superb, and they don't need to have their barrels recrowned because they are already hand crowned at the factory.
Still, I have read numerous articles regarding rifles made by Jarrett, Sisk, McMillan, HS Precision, Nesika Bay, etc., and often dream about owning one. Maybe some day. :grin:
