44AMP, the military's phobia about a dirty weapon was never based on accuracy with or without a copper fouled bore. 'Twas based on wanting weapon users to ensure their weapon was in good enough condition to shoot without a stoppage. There was more to keep clean and cared for than just the bore. Corrosion was the biggest concern.

Besides, a good centerfire sporting barrel will shoot several hundred shots without cleaning before accuracy gets worse than 1 MOA. And military combat rifle barrels will shoot 2 to 3 MOA for a thousand or more rounds of military ammo without cleaning; that's typically their accuracy spec.
