I understand .223/5.56 AR's are a great rifle to teach youngsters shooting, but when it comes to using one on deer the shooter needs to be very confident of the ability to put the bullet where it needs to go, and ammo choice is critical. The 5.56 is marginal when it comes to stopping/killing power as reinforced by our own military ,, they have complained for years about the round. Will it kill a deer ? sure ! but your chances of it running off and you not finding it increase greatly when using a .223 as compared to something like a .243 or 7mm08 or .308. I own an AR in 5.56 , and also one in .300blkout, even with the .300bo the bullet choice is critical. There is something to be said for larger capacity cartridges shooting heavier bullets.
