Hi all......I inherited a Colt New Service in .44-40 from an old cowboy uncle several years ago, and have shot up the several hundred of his handloads that came with the gun. I have been told that most data listed for modern designs may build too much pressure for an old timer like this......the cylinder walls are pretty thin! I want to keep shooting her, but dont want to risk damage to the gun or myself.........advice? Thanks in advance!
