PS. The overiding decisive factor that makes it wrong is, "What would a soldier feel more confident with in a warzone?" Right there is the truthful answer.

This would increase muzzle velocity and accuracy and more mimic the bolt action rifle. A bolt action rifle levers that center fire bullet in place like a vise.
