High Velocity Ammunitions, Silencer

HV 5.56 Rifle Ammo
HV Pistol Ammo
High Velocity Arrow

What damage difference with normal bullets?
much less?

How much amount of damage they produce less?

You need to update this information in WIKI

I wonder if silencer is actually useful if u use HV with it

Silencers are great on the shotguns, you can 1 shot people without anyone noticing
