I dont know much about Canadian laws but if I were you I would just buy the reloading components for that caliber and make my own ammo for it.Does any one know where ammo for a colt 41 can be purchased in Canada?
The .41 Colt is closer to the .38 Special than to the .41 Magnum. I had a chart at one time that told how to make old cartridges from new. Will try to locate it. Maybe the .38 S&W case could be used to make the .41 Short Colt.Could probably trim down 41 mag cases. I'm just guessing on that though I'm sure there are some experts here that have some good answers.
