Hey, Jim. I belong to another forum, shotgunworld.com, that has followed this matter very closely for the last two years. The guys there have had some accuracy issues with .50 cal jacketed bullets and most use .512-.515 lead bullets in 425-500 grains to get optimum accuracy. It is a 20-page thread under the "slug shooters" forum. I have not bought any of new sabots yet as I am still using up my old gray ones. Have 2 bags left.
