A lot of good comments. I believe that the primary reason for the longer stock is that the fitter noticed that I crawl the stock forward when I mount a gun. He kept trying to adjust so that the contact point between cheek and stock was back off the comb. The fitter used iron sighted rifles with a variety of stock heights to find one that worked to place the sights in alignment. I have always noticed that most guns I shoulder have the front sight way up out of the rear notch. The drop and cast he picked lined me up perfectly with the irons. I have several guns in the shop with that much pull. I'm going to have one bent to his dimensions and try it.
