you might think " Primed Cryo Rounds is better"-but you won't status puncture for armor strip
can guess, you wanna use [Galvanized Scope]... for AoE weapon, with every time exploding by ricochet projectile... don't kidding like that anymore
[Vigilante Armaments] instead [Piercing Caliber] makes dps less and down chance proc of puncture from 40% to 25% for every status proc (it's stupid idea to try remove [Piercing Caliber])
[Bladed Rounds] maybe better for high lvl enemy, but I like +80% chance status and 60% crit dmg from Hammer Shot more than just 120% crit dmg

take only evolution with +100% multishot from second and -20% armor from last (third is nothing, really)

P.S. If someone have bigger dps build, it doesn't mean my build is worse, cuz bigger numbers =/= bigger REAL dmg
