Yes, there were some rifles stamped 7mm Express. I have seen a few older Remington 760's and 7600's with that stamp. I also believe some early Rem 700's had 7mm express stamped on barrels.
I would like to find one stamped 7mm Express. An article back in the early 80's in either a Shooters Bible or Gun Digest about the 7mm Express piqued my interest in the cartridge. Like the sound of the 7mm Express more than 280.
