My opinion - any factory Contender or Encore barrel is a crap shoot. Some will shoot, some will not. I love my Contenders, still hashing out the Encore business. I have been fooling around with TCs the better part of 40 years. If I wanted a barrel that would shoot, no question, I bought a Bullberry. Unfortunately, other than used, that option is now gone. Their hanger system seemed to help with the unexplainable fliers that occasionally happened. Gary Reeder’s barrels are great - at least the ones I’ve tried. As far as bench technique, find what works for you. I don’t rest the butt on anything, same with my XPs. It works for me.
