Rios are a good choice but do dirty your double a bit. I've had one not to ignite in several thousand rounds(lead) and on 2 occasions have had steel to roll out the end of the barrel, leaving the wad in the barrel, after the steel cartridge were exposed to moisture. If you use steel Rios, always have a wooden dowel handy when you are in a swamp.

Kind Regards,
