Other thing about RWS caps is the fired ones generally come off real easy cause they split up from being so hot. But do not come apart and throw crap in your eyes.
CCI #11 caps fit tight enough that they need to be pried off the nipple with a knife/screwdriver to remove if not fired. They never give trouble after firing as they always split open. I have used nothing but hot shot nipples so fit/performance may be dependent on what brand nipple is used. I have yet to have a misfire or hangfire with them after using them to ignite 10-12 pounds of Goex FFFG in my T/C Hawken and I get excellent accuracy. I have used RWS caps in the past and saw no advantage over CCI.
