I purchased a Traditions Pursuit LT this year and have always used the powerbelt 245 gr. While sighting in this new rifle, I couldn't keep even a 7" group. I decided to try TC shockwaves and put the next 7 shots within a 2" group. Knowing the rifle was sighted in accurately I tried the powerbelts and again all over the target. I have switched. Just seemed too inconsistant for me.
