I was planning to use my .357 magnum carbine for deer last year, then the SK regs changed. I certainly have not been harmed by the legislation, since I have several other ( much more suitable) rifles to use for hunting deer, but I just wanted to give the little carbine a job to do. The people who were really upset were those who hunted with their granddad's .44-40. That traditional round and the .45 colt are pretty capable deer cartridges at close range, not sure why they were banned and at the same time I can now hunt hoofed game and bears with a .222 Remington.
I'm pretty sure Manitoba hunters can use .22 centerfires for deer, but don't know more specifics.
