Bullets dinking off of things

mostly for armor with high hardness values where when a bullet hits that said armor if it is a platemail or army helmet, and the armor penetration is not high enough, the bullet should just ricochet off, leaving you unharmed,

but i would keep it to a hardness value over a protection value, cause i really don’t see bullets ricocheting off of a Kevlar vest

At certain angles they would, but I think most of the time the bullets just mash themselves flat against the armor, while also putting a serious dent into it depending on the armor type. It would be really cool with power armor though.

Perhaphs a tag that gives most bullets a 75 percent chance of just simply bouncing off of power armor
