I can't speak for the locker pin....................... but their bullets kick butt!
I've not, to date, found anything that shoots better in my Knight - and they have devastated everything I've shot with them. My rifle prefers their QT sabots, the Dead Centers just aren't as accurate for some reason in my gun.
That is some excellent marksmanship!! I've had similar results with the 40/45cal QT's as well. And the QT's load easier and shoot tighter groups than the DeadCenters in my 45cal as well :wink:
