You see a few wildcats based off the .223 and 222 rem mag out west here, and some guys are going nutz on the 6ARC, 6.5 Grendel and the smaller cased stuff, but in reality , it's all about what you want too shoot , much like hot rodding and custom bikes.
Personally, I am having a great time these days with my 6mmBR , but I shoot single shot mach rifles in those little cartridges- hunting wise I use bigger stuff in my falling blocks, the smallest these days being a .260 on a Highwall.
The AR style stuff may catch on down south of the Border but I see them as a bit of an odd duck up here.
