This mod is absolutely fantastic, however piercing ammo feels very overpowered due to it's piercing effect. It can make any early to mid game biter threats really easy to deal with, even on death world. Would it be possible to configure whether piercing ammo actually pierces or have the piercing projectile lose damage each time it pierces an enemy? I recently played a non-modded Factorio run and saw how much harder (and more exciting) it was when one turret with piercing ammo couldn't defend a whole wave by itself. Don't get me wrong, seeing bullets pierce through a whole wave of biters is really satisfying, but I'm trying to make this game harder.
