I shoot the SW at 2100 in the Triumph and 2250 in the Omega. The Greenhil formuls as modified by the military [I have the program] gives me 2400 as the ideal velocity. As the 200gr SW and the 200gr XTP are the most accurate bullets in both guns consistantly that any thing over 2100 should work ok, I am hoping that the new powder will add some velocity and maybe some to the long range accuracy[ some time especally when there is a bit of breeze my groups open up some at 150 yds I would like to be able to keep a minute of angle out to 200yds .
