I had a Square Deal 15 or 20 years ago but I just used it, never changed calibers or anything. So now I bought a used Square Deal set up for .44 Mag with a conversion unit for .45 Colt. The installed dies seem to be mounted on a blue plate and there is a similar plate in the package with the .45 Colt dies. Does this infer I can detach and remove the .44 Mag dies as one unit and install the .45 Colt dies in a similar manner? Just curious as I intend to sell it anyway.
