I have a colt saa from the 1880s based on sn. It is marked .44cf doing research i found that colt had the 44 colt, and 44-40/ 44wcf. There is alspo the concern of the 44 remington. But i cant find which one i need, intent is to get a set of cartridges to shoot light loads once a gs evaluates the pistol. Does anyone have any data chamberings on this as i cannot find good info.
