utahrum300, take off the new prongs and put back on the old with the teflon tubes OR put the teflon tubes on the new prongs. That thick felt looks too thick to me, it might be giving you too much variance. Just a thought. Email me your home address and I will send you a piece of the 3/32" stuff I put on my shelf exactly where the prongs contact the shelf. I don't hear any click from the contact now......all I hear is the shot.
