The fragmenting 12 ga. Slug is one of the best slugs we have seen tested. The pieces of this slug can break apart and go all the way through the ballistic jell!
While some of these types of designer slugs are not very accurate, the Twister is very accurate. The flight of the slug is not perfect, but the accuracy is still there.
Watch the guys from TAOFLEDERMAUS test one of the best slugs they have seen.
