Blackhorn all the way! I use 100 gr of blackhorn by volume and a hornady 250 sst. Smashed a 5pt'er at 10 yards from my tree 2 years ago. The deer was toast, he didn't go anywhere. I am not sure of the sst's out of my shotgun as I feel I didn't get a good blood trail/ exit would, but the deer dropped 40 yards from the hit. I will keep using the sst's in my ML until they give me a reason to switch.
