Bloody Mess Only Procs with certain guns (Shotguns/Scatterguns/Explosive weapons)

[straightface87]

So the bloody mess perk is a lot of fun in my opinion, when I hit something point blank with my explosive combat shotgun and it explodes to bloody pulp it's really satisfying.

 

However when I shoot a feral from a few meters out with the tiny little Deliverer silenced 10mm and it happens it just doesn't feel right. Could someone make a mod where the damage bonus is unchanged, but enemies only pop with certain guns where it makes sense that they could? Like it only happens with shotguns or 50 cal or whatever. You get what I mean.
