Volcano vs Cobra

Im running all maxed steady, impact, and do or die. My gear is a Bee, leg. Soldier, and explosive relic. Factoring all this in, would the Volcano or Cobra do more damage in a basic body shot? I would test it but dont have either. Thank you! And unfortunately im not familiar with the max damage of both.

The Cobra is only affected by explosive and gun damage buffs so all the grenade buffs you have will not affect it. However in terms of Jakobs it hits rather hard on Axton with a high quality of explosive relic, being second only to the Elephant Gun.

I have no knowledge on the Volcano.

I gave a detailed run down of the volcano vs snider that I need to finish.
