Those were the slugs of choice this year! My H@R ultra seemed to like them the most. I managed to shoot 3 does with them 40 to 80 yards. One through both shoulders and one quartering hard towards me. Put it right through the point of her shoulder. maximum distances they ran was 40yds. And complete pass throughs and def took everything out in there way! I'm not parcel to them and would like to try them at longer ranges but they do do there job IMO
