Ability to hand-load heavier, longer projectiles. More accurate. Vepr is more accurate than a regular AK, due to a thicker receiver. Bolt gun action is as stiff as action can be.I have several AK 47s. I don't see how this round improves much in a bolt gun. But I want one.
I love chrome-plating in my AKs, but it does bring down accuracy. Since I will not shoot bolt gun as much as AK, I am not concerned with barrel longevity.
