The acceptable standard for battle rifle accuracy in the early to mid 1900s was 2 Minutes of Angle. If it shot better than that, fine but not required. Most countries marksmans (sniper if you will) rifles were simply regular battle rifles that shoot better than the others of it's kind. They were all made on the same machines by the same workers. The UK's No.4 Mk1 (T) being a notable exeption as they were worked over by Holland & Holland. The wood on my M-1903 is walnut while the wood on the Mauser is a birch or possibly beech. The Mauser has more noticable machine and tooling marks than the '03 and so on. Not all Mausers shot great and not all Springfields were less accurate. Every rifle is different even when made by the same man on the day on the same machines. If you could my two rifles, you would see what I mean.
