I'm with you Nobade. I had such a liner in my Pedersoli Blue Ridge and was perfectly happy with it. I heard so may claims for the White Lightning that I decided to try it just to see what all the talk was about. Terrible mistake, I had misfire after hang fire after misfire, my rifle has never been the same. Once you tap your barrel to that odd-ball 32 pitch thread you can't use any other liner unless going up to a larger size and the 5/16x32 was as large as a barrel flat could stand. I've tried to make the White Lightning work like my old liner and have gotten some improvement but still not to match my old liner with deep recess on the inside and a shallow recess on the outside.
