Seeing some of the builds on here, the authors of which I rely on regularly, I didn't like the inflexibility of their builds this time, that all slots were formed, which results with limited variety of damage elements, what I don't like most. Pushing for max damage, they lost all versatility. As a result, I aimed to ensure exactly that with this build. As a result, the build has one slot without a forma and theoretically it works only if we use at least one 60 mod. As a result, you can have a greater variety of damage elements while losing very little damage.

Damage variety eg.:

A. Jolt + Pathogenic Rounds + Primed Heated Charge - Corrosive + Fire
B. Frostbite + Pathogenic Rounds + Primed Heated Charge - Viral + Fire
C. Frostbite + Convulsion + Primed Heated Charge - Magnetic + Fire

Just if You will wish to make something like Radiation + Cold You would need to move formed slot.

D. Jolt + Primed Heated Charge + Deep Freeze = Radiation + Cold
E. Pistol Pestilence + Primed Heated Charge + Deep Freeze = Gas + Cold

I don't suggest to remove Primed Heated Charge as large part of damage you gain from it.
