Nice shooting, I believe it isn't so much that you are shooting long sabots, as it is that they aren't the ribbed sabot. I shoot the Harvester Black Short sabots with my 333 gr. hard cast at an 85 to 90 gr. Bh209 equivalent load. IMHO - There is nothing on this continent that can survive your load of 90Gr V BH209 and the 300 gr Gold Dot bullet as long as it is placed somewhere near the Pulmonary Pumper..
