As the service charge was given as 3.8 gramm Gewehr Blaettchen Pulver = 58.6
gr rifle flake powder and a steel jacketed bullet, the rifle was originally
proofed for the 10.75x63
The Birmingham proofmarks on this rifle are confusing: The case length is given as 2.48", that is 63 mm, but the service load is 347 gr bullet and 62 grs NC powder.
