Caps?

[Mr. 16 gauge]

For you caplock shooters, is there anyone here who has a
preference for a certain brand of caps? I've done well with CCI, and prefer to use their 'magnum' cap while hunting in cold conditions, but I' haven't used much in the way of other manufacturers......I think that the only other ones I've tried were Remingtons and CVAs (which were a European make...Spain or Italy....and didn't work for crap!). I don't even know who makes other brands out there; I thought RWS (Germany?) made some?

On a similar note: Is there anyone out there that makes their own caps? I thought I heard or read somewhere of a device that will make caps out of old beer and soda cans.....thought it might make for an interesting off season project.
