Oh come on now......it goes without saying we're talking about AR-15's and their variants (M4 et al.)and the relatively medium range effective cartridges chambered therein. I realize that there are all sorts of rifles chambered for large hunting cartridges that are based on the original AR-15. I did a quick search and indeed found "AR" chambered in 300 WM. If someone wants to pay $2000 - $6000 for a 10-12 lb. (bare) rifle with which to hunt big game, I fully support them.
The cartridges that are AR15 chambered that will fit in the 5.56-length magazine are limited in their application. The original chambering, the .223, was never considered more than a medium range varmint cartridge until AR-15's became so popular. Did the platform somehow change the ballistics of the .223?? Nope. Some of the other cartridges are quite interesting, but they are all limited in range. I suppose if someone wants to hunt elk with an AR-15 and understands the limits of the cartridge, more power to 'em!
All that aside, the 450 BM is quite interesting, but why they decided it should use .452" (pistol) bullets completely escapes me.

A .430'' dia bullet would have been more useful for reloaders. It's really too bad that the magazines of AR-15's limit cartridge design.
