45 ACP or 45 Colt? The early 45/70 and 45 Colt and S&W ammunition produced by government arsenals were inside primed. The 45/70 ran from introduction until 1882 but I don't know just when it was stopped in the 45 S&W cartridge (the issue cartridge after 1875 was the 45 S&W cartridge rather than the 45 Colt as the S&W Schofield had been adopted as a sidearm along with the Colt 1873 and the S&W cartridge was chosen to simplify logistics). An inside primed 45 ACP would be pretty strange as that process had been stopped a few decades before that round had been developed.
