I'm the same, as I said. Probably at least half the rifles I own require some kind of case forming. A few require extensive forming and lathe work. I'm working with a German double rifle right now for which the cases can only be made from 30R Blaser. It is pre-WWI and was originally chambered for the 8 X 62R Vierordt. In 1941 it was evidently re-chambered and re-proofed in Prague, Czechoslovakia for the 8 X 65R Brenneke. As there is no importers mark we assume it is a war trophy. It appears that some half baked gunsmith on this side of the Atlantic tried to ream out the chambers for who knows what. It certainly doesn't appear to be up to the usual Czech or German standard. Neither me nor any of my German Gun Collector Assn. friends can prove that, obviously, but it's the only thing we can think of for the butchered chambers....and we might all be nuts too. It is close enough to the 30R Blaser in head size and body taper that cases can be made to work by necking up, shortening the case, turning the neck and fire forming. As marlinman said, it can be a lot of work but I enjoy doing it. Had this double rifle been for an easily acquired cartridge I doubt I could have afforded it.
