Hey there! With the new changes to Critical Deceleration and the introduction of galvanized mods, primaries in general are really strong.

Replace the 60/60 toxin with 90 toxin for higher DPS, but i wouldn't put in any primed elemental, [Chilling Reload] is a very important utility mod and cold mixes badly with [Primed Charged Shell] to say the least.

Of course this is all very subjective and you could go for a big boi damage setup, but im happy with this and its not like im gonna bring this to lv1000 content.
