I think in a time of marginally performing bullets it may have mattered. So much of what we believe today stems from corrosive gunpowder’s stocks designed for open sites and bullets with unreliable, poor mechanical performance. so much of this industry is designed around what granddad told Pappy and Pappy told me with no recognition of the innovation in between.
He also references that he was not allowed to carry a sidearm during the hunt because of local regulations. I’m guessing there were other weapon restrictions as well.
