Solved your Gjallarhorn problem. Let the gunsmith reforge Rocket Launchers with Wolfpack Rounds (or whatever perk with clusters that track for extra damage) in the mix.
Thanks.

Wolfpack is the gjhallahorns exotic perk. Since it's an exotic perk the closest thing we can get is a regular cluster bomb that doesn't track. So I don't see them adding that in for regular weapons if it's an exotic perk.
