I tried dukino by zer0 (with twister and b0re) But icould not find b0re effect and damage.so maybe Each projectile of 1shot of twister cant hit general enemy(without multi hit box) again. except saturn , omgwtf etc...
The Twister's pellets bore through enemies, usually for no additional damage. But, for big-ass enemies like OMG WTF or Bunker, the Twister's pellets go into their hitboxes, ricochet, and home in to the bosses' turret(s). That's the part that does a lot of damage and why it stopped working when the Twister pellets eventually worked their way to OMG WTF's turret and killed the turret.
