In my CVA accura v2 I'm shooting the red crush rib sabot by harvester. My bullet is the a 250 grain hornady sst. The black crush ribs were to loose. Kind of loose with knurled bullets. I do have the harvester black smooth sabots. Haven't shot them enough.
I couldn't get the pt golds to group worth a darn in the red crush rib. Switched to the sst since they were in my box. Finally had great groups. After deer season I'm going to try shooting the scorpion pt golds with black smooth sabot. All shot with blackhorn powder.
