Penta Weak In Void?

[ArmyOfFun]

I have a six forma penta that competes with the dmg of Ogris now that Ogris explosions dmgs are calculated differently.

I hit 7/9k-18k when built for 75% dmg bonus specifically per faction, but in the void I'm doing 180 dmg with 75% bonus gas to grineer heavy gunners or 1.5k with corrosive.  I get about 500 dmg to most other mobs and the occasional 6k (that should at least be expected)

 

Both Ogris and the Penta can hit these numbers.  They are different Ogris is a straight shot charge up weapon and the Penta heavy arcing high angle /trick shot weapon.  I've only experienced this lapse in dmg with the Penta any clue what the problem is?

 

11.3.2 now I'm hitting 5-6k on normal enemies at 30, expected.  On Heavy Gunners in void I'm still hitting 580 dmg with corrosive which is now 50% bonus to armor.
