Well it appears I just acquired an early 1875 Remington revolver(sorry no pictures yet) in it's native centerfire 44 Remington caliber. I appreciate 44-40 is similar but it definitely won't chamber in the new gun. My understanding is the 44 Rem brass rim is thinner and the brass actually tapers down towards the bullet, would the shorter 44 Russian round fit with some modification? I am dead curious how folks are reloading? brass, dies? Many thanks in advance.
