I had another thread about how CCI had changed their musket caps to a new weak power cap.
I went out an found some RWS musket caps. I can say they are WAY more powerful than the CCI new musket caps.
The CCI seem to be about the same power as regular #11 caps. That is pathitic. The # 11 mags are louder than the CCI muskets.
So, have faith if you use these to hunt with. Get the RWS.
