RE: Hamilton No. 2722 (RWW)
C120,
The 7.5 French Mas is a Pre WWII military cartridge. It has about the same ballistics as the .308 win. Where I live they sold these French rifles a few years back, I think it was a M36 or something. They were " new" guns that someone had found and was importing. I would pass on the 7.5 French finding brass is difficult and the rifles are of poor quality. The ammo out there has mercuric primers to.
The other Remingtons I am not sure of.
