Dunno what you are replying to.
I said nothing about the 5.56mm, nor will I. I was trained on and remain a 7.62mm rifle type.
Sorry for the miscommunication, I meant only to highlight the advantages of having a .308 or 30.06 ( .30 cal) with “ exotic” ammo when the vast majority of the public ( good and bad) are equipping themselves with the underpowered 5.56 AR’s. I realize cost maybe playing a factor in purchasing a .30 cal rifle semi, but that said, a 7.62x 54R Moisin Nagant bolt gun is still cheap, has cover removing and AP advantages, and surplus Russian AP is still available.
