Gents: Afteer reading the posts on the above subject, I looked thru several old Rifle Score Books which I have from the the 20's to the Early 1940's. I found that in 3 cases low numbeer springfields were being fired. One from August 1927 at Camp Perry was a member of the Ohio State Rifle team and he was using Rifle No. 236779. Ammo used wass FA 1926. Anoother from 1923, Plattsburg, NY shooter using 184404 and USC 1918 ammo. This is a very small sample, but one might conclude that low number springfields were in common use during that time. I'm sure there are a large number of members who have similar books data from which might shed more light on the subject if a much larger sample was available.
