I have used the HS Strut Undertaker xtrafull on three different guns, with 3" wwsupreme buffered #6 loads. One was no head at 15yds,beak and pcs of skin, one was a mushy mess at 30 yds, one at 53yds was just plain dead. On the Redhead turkey target at 50 yds, I get 13-20 kill pellets , not feather cutters (that would bring it up to 30-43).
