The poor quality of CCI isn't them "not going off", it's a lack of sufficient pressure to insure proper and complete ignition of the charge. If you think I'm off base, do the experiment. Test CCI against RWS and Scheutzen head to head for accuracy. Change nothing but the cap. CCI will deliver more flyers than both RWS and Scheutzen combined.
As for needing a "second hit", assuming the caps are properly stored, that's a function of the nipple geometry and condition of the recess in the hammer. Many have complained that Scheutzen caps have this issue but the real culprit is the Scheutzen caps are gilded steel and less forgiving of errors in nipple geometry than RWS. A very slight change in the profile of the nipple and Scheutzen are just as reliable as RWS.
