Cayugad, I got to pop a lot of caps last fall when working on my pivot hammer conversion for my White. I had to test the thing to see if it would pop a cap. So I started with the cheap stuff first, remingtons then cci because I didn't want to use up all of the RWS I was saving for hunting. But in the end I ended up using all the cheap stuff and had to use the RWS. First thing I noticed with the RWS, poping them off in the house, that the RWS were much louder than the others, and the caps would disintegrate (RWS) where the others would go pop but still be intact. Try it sometime, get some different caps and pop them of in the house or garage, it will be appearent which ones are more potent.
