Regarding East Tennessee Hillbilly’s otherwise excellent summary of reloading: In the back of the Arsenal of Democracy I keep a case of each caliber I shoot. The 7.5 Swiss cartridge has a wider case, thicker base and thicker rim than .308. I don’t believe it’s possible to fabricate 7.5 Swiss cartridges from .308. – Michael Z. Williamson
JWR Replies: I have read that .284 Winchester brass can be re-formed to 7.5 Swiss without much difficultly. The same thread mentions that Graf & Sons sells virgin Boxer-primed 7.5 Swiss brass that they had made up with their own head stamp.
