I am getting a ar soon and would like to use it for deer hunting also. I have read a lot about both and am leaning towards a RRA in 6.8 but I would like to here more pros and cons. Also is everybody crimping their ar reloads or not. Personally I don't crimp anything in rifle cartridge. Also the 6.5 and 6.8 use the same lower ar the .223 so I will also get a .223 upper also.
Hunt with your kids now. So that you don't have to hunt for them later
