Getting "measured" is just a starting point, not the final measurements people think. It, the fitted measurement is used to set up a stock so you shoot the gun at either a pattern plate, clay targets or live birds. A good fitter will set his try gun up, let you shoot it if possible and make more adjustments from there. Many times he readjust it and lets you try the refined stock. Unless you got to shoot the new stock configuration you are just going by someones opinion of what you need to shoot and he has never seen you shoot anything in your life. How confident are you in that?
Shooting style, technique, form or what ever you want to call it needs to be taken into account. Low gun, stock semi pre mounted, pre mounted, light clothes, heavy clothes, seated in a duck blind or layout blind, hat type, glasses worn all go into what you need. Just mounting a try gun in a shop and seeing what gets you eye lined up with the front bead is not a real fitting.
Put simply if I did not get to shoot the new "special", and sounds like totally different measurements, I would never have them made into bespoke guns. Why would you do it? Find a gun to alter the stock on and shoot it first. Refine as needed, then order you custom stocks.
