It's about 1 turn from venting. How much difference in FPS velocity do you usually get in one turn on a 68 Classic?
side note: I gotta say, I'm VERY happy with the performance of my new J&J Ceramic! I ran my test shots through two different barrels and the Ceramic REALLY shoots straight! I am going to OWN in my next game!
