Your barrel is very similar to my Triumph, by velocity I have come to believe that the super pellets are similar to 120 gr of loose 777-FF which with most loads is where mine will lose it group and become eratic. I have also had poor results for the Superglidesabots most of the people that I have heard from with two exceptions have also had poor results from theSuperglides. I also find the expense perhaps I sould say extra expense of both the Super pellets and the Superglides completely unnecessary as mine will tear sigle ragged hole with 110gr 777-FFwith several bullets and the Crush Rib sabot .
