You have a choice of XTP or Shock wave in a 10mm[ 40cal.] by using the blue sabot from MMP; I have been using the SW for several years and believe that they are one of the easy bullets to get to shoot accurate, I have taken 2 deer and2 boar with them with excellant results, I use 150gr of RS in the Omega but they will shoot very good groups with 110 or even 100, in my new Triumph the best load I have tried to date is 100gr 777-FF it has a 1.1 inch average for all the groups I have shot, next time out to the range I mean to try 110.Lee
