Logic doesn't apply when it comes to why one firearm or calibre is allowed and another isn't. No semi-auto's allowed in PA, for example.
Up here, in parts of the Province(mostly Southwestern Ontario), using any centerfire greater than .275 is illegal at any time for any hunting(range shooting doesn't count). The name of the cartridge is the determining factor, not the actual bullet diameter. So a .275 Weatherby is ok, but a .280 Remington is not. Speculation has it that it was enacted to prevent W.W. I vets from using surplus .303's for deer hunting. Mind you, having driven around the back roads a bit, there's a building of some type every 2-300 yards in every direction. Even a .22lr is dangerous.
There are 'shotguns only' areas and some 'archery/muzzleloader only' areas too. Usually close to heavily built up areas, but there's no logic to any of it.
