I use them with excellent results. In the .45 I use the 200 gr 10mm bullet in a Harvester blue CR sabot. For the .50 I use the 300 gr .429" and a green Harvester CR sabot. The deer I shot with them were never DRT but only traveled a short distance before piling up. But then again, I always aim for a behind the shoulder shot taking out the lungs. And judging by the exit wounds expansion was very good.
