Lonewolf, I get a kick out of people that say a 1:38 twist gun cannot shoot sabots! And you are getting under 2inches at 100 yards, excellent! A tech at TC told me that they went to 1:28 mostly due to popularity of the fast twist guns. They found 1:38 to be adequate for the most part. They also pointed out the faster twist is harder to clean.. My buddy with a knight at 1:22 can attest to that...
