I couldn't get the Dead Center's to shoot any smaller than a 6 inch group at 50 yards out of my Knight, powder combos from 90 to 120 grains. SST's shot under 1.5" groups at 50 with 110 gr. I've heard a lot about SST's not opening up, but I'm not sure how much of that is based on fact or hearsay (other than those video's, of course). I shot a buck with them, but in the head at 27 yards, so I can't comment on how the bullet expanded being as I didn't find it. I'm going to stick with the SST's while I still have so many of them, and then maybe look at the Barnes.
