I have a Triump and have tried a wide range of loads in it including some 150gr 777 other than the fact that it shoots some loads better than others which I believe you will find true of any fire arm. I have several loads that will shoot minute of angle and believe that to expect more of a muzzle loader than that is foolish. Any one of my favorite loads will ring a 20inch gong at 240 yds [ my longest target] real regular as long as I dont have to fight a strong gusty wind. I shoot my Triumph in preferance to any other inlines, I like my Knight and my Omega but I dont have wheels for the Knight and the Omega is a lot more of a pain to clean so the Triumph goes most often.
