Quote: Older guns can be lesser accurate for all sorts of reasons as we know. Firstly wear. Throat or muzzle. Worn rifling. Putting and corrosion. Different free bore, possibly excessive. Differing bore calibrescthan the "standard". Same for chamber dimensions. Modern rifles are made to greater standardisation. Accuracy imo is a great factor of uniformity. In every aspect. Bullets, brass, powder charge and composition, primer. Plus the rifle design, chamber, obviously the barrel and bullet are huge factors. |
