My next try with the .40/200 grain Lehighs will be out of the Renegade's .45 caliber GM LRH barrel. It has a 1:30 twist and gives me two-inch 100 yard groups with .40/200 grain XTPs over 80 grains T7 FFG. Velocity with that load is 1760 fps.
The 200grn Lehigh bullet wont stabilize going that slow in a 1/30 twist. Your XTP is a much shorter bullet and it will at the lower velocities.
