If you hunt exclusively in North America, there is probably little reason to go reason to go to a 50mm objective. But there are good reasons why the rest of the world hunts with larger objectives.
OK, I'll bite. What are the good reasons hunters outside North America use 50 mm objectives, while they're not necessary for North America?
Because nobody else hunts/shoots with curfews - it is a bit of a North American oddity. In much of the rest of the world, a lot of hunting actually occurs outside of legal hunting hours in the USA and Canada - even in the middle of the night. This results in very different optics in the rest of the world - not just with respect to larger objectives, but also lens coatings that favour low light performance. It is probably THE major reason why European optics are so different to American, but is frequently overlooked.
