rem270, did you not find any blood, just curious how you lost 3 deer. Did the platinums shoot good at the range or where they all over the place? I know from personel exsperiance that the 223's will kill deer so I'm just curious as to what happened. The deer I lost using them was my fault, I hit him too far forward in the shoulder, had a good blood trail but he got into some land that we didn't have permission to hunt. I saw him a couple times and he was dragging his front leg, probably broke the shoulder, but missed the vitals.
