Gentlemen,

just some information about the 8x60S (kuduae left nothing over to be explained on the technical side...very informative...thank you!).

Cartridge cases can be had from RWS for about 140 €uro/100 cases (i.e. www.johannsen-jagd.de)
and that seems not to be very much in regard of shooting this classic caliber!
My favourite load consists of Rottweil R907 and the Norma 196grs PPC Vulcan or the 196grs TIG.
Best precision was obtained with the RWS 181grs Doppelkern and Kemira N140, but pressure seems to be a little high at 810 m/s. The only RWS factory load with the RWS DK was chronographed at 815 m/s out of the same rifle.

The german gunsmith Andre Fuhrmann (google for fuhrmann-jagdwaffen)in Jena can enlarge barrels from .318" to .323" diameter. After the enlargement a proof test of the new-caliber-barrel is mandatory, the passing of the test will be certificated by the proof mark stamp.

best regards
Rolf
