The status chance is too low for a proper viral Hunter Munitions build. Better to build for raw damage and take advantage of the excellent crit stats. You have to be zoomed in while the explosion goes off for Bladed Rounds to work properly, which is jank as fuck but it's a 58% damage increase- more than a primed faction mod. Speaking of faction mods, replace Vile Acceleration with a faction mod if you're already getting fire rate from Arcane Acceleration. Obviously use viral instead of magnetic for grineer and bring an AoE strip.
