Get a Schuster M1 adjustable gas cylinder plug and shoot whatever round you like, and don't worry about damaging anything. A cheaper option than reloading. If you can't find them in Canada it's easy to ship from the states like anything else. No import/export concerns. Looking at approximately $70 after exchange and shipping
Saying that, I reload for everything that I shoot with the exception of 25-20, and I'll still use the adjustable plug in the Garand because sometimes it's nice to not have to chase the brass
