223 is among my very favorite cartridges my friend. Although I use it in the AR platform. I’ve hand built & owned a horde of AR15’s over the last 17 years, and all but 2 were chambered 223/5.56. While I’ve never had a Bolt Gun in 223 I know what it does in my high end AR15’s. And I also know that performance can only be furthered in a Bolt Gun. Trainer says you? HA, says I!
