When guns were first invented, the shooter had to adapt to what the maker made. Next, it was discovered that certain stock dimensions made for easier shooting. Then it was discovered that a stock made for an individual (bespoke) was easiest to shoot well. Gradually, those who had great social pressure to shoot well gravitated to a single gunmaker who becme expert in fitting that individual. The relationship of shooter and gunmaker got devalued in the development of manufactured guns, length measuring tools and try guns. The American picture of knowing LOP, drops, and, maybe, cast, seriously short changes a number of small variations in stocking which a gunmaker would adjust to the shooter. So, we are better with custom stocking dimensions, but best with a relationship between the shooter and the stocker. Hopefully, a relationship where the gun is shot at pattern plates extensively and the stock fine tuned before it is declared finished.
