I use the 300 gr Expanders with 100 grains of powder. I have never recovered a bullet as they blow right through with a very large exit hole. I switched from the 240 xtp as one blew up on me as the expoanders will not fragment. Accuracy is pretty good but was better before they began using thinner sabots. Another benefit for me is that they shoot in the same place the first shot with a clean barrel. Groups are fair at 2" at 100 yards.
