Gentlemen,

according to a german proof house information, the barrel of a 11,2x72 Schüler has the dimensions:
10,85mm bore dia. and 11,25mm for the rifling.

I shoot the .440 bulets from Woodleigh (400grs)and Degol (330 and 400grs) with good precision.
Unfortunately the Woodleigh bullets have no crimping cannelure.
I had no luck with Bertram Brass, because the body dimensions were not matching my rifle chamber.
Horneber brass functions without any problems.

Congratulation for your "new" rifle!

best regards
Rolf
