First, your probably gonna want Remington #10 caps for pretty much any ASM if you can get em... If not, go ahead and try the #10 CCIs if you can get them.. Just understand, they are cheaper because.. well.. they ARE cheaper. You would do well to listen to the advice here about turning ya gun before cocking it... This goes DOUBLE so when using CCIs. I wouldnt use em as a CC or an EDC at all, as has been mentioned, if #11 is all you can get (and it does seem that ANY #10s are about as common as hens teeth in local stores these days) then, again, as has been stated youd be better off looking into replacement nipples that wil actually fit what you have access to. You can order whatever ya need online, BUT youll pay a hazmet fee for it (usually around $20).
Now.. that being said... Just some friendly advice from someone who DOES EDC one of these weapons quite a bit (and I have had a LOT of side wise glances because of it LoL!) Im not sure that youre barking up the right tree.
First, you admit that youre not very experienced with our old C&B wheelguns... And thats OK! Everybody has to start somewhere bro! NONE of us where experts the first time we picked one up, ya know? BUT.. You said ya wanted to CC this thing.. NOT to EDC it, but CC. Concealed carry denotes that you are carrying solely for Personal Protection. As in, you may find yourself facing another human being. Being a beginner, Cap and Ball revolers are simply NOT the way to go for that if you have ANY better option.
Some people DONT have any better option, and I can sure as hell respect that... But if ya DO have ANY better option, THAT is the option I would recommended.. I spent a LOT of time learning these sidearms and can tell you first hand that C&B every day carry is not for the novice.
Im also a HUGE proponent of 777.. Dont care WHAT ya gonna carry for a real world working gun, its pretty much GOTTA have 777 or 209 if its gonna be called upon for life saving measures (and there are are a BUNCH ceviots that go along with 209!).
THAT being said though.. You are STILL attempting to concealed carry a .31. I dont care if you are powering it with a small nuclear reactor, nothing in the WORLD is going to change the fact that its a .31! When it comes to personal protection, or protection of loved ones, you are simply NEVER going to get it from a .31 C&B. Yes, "back in the day" people carried them all the time... There was a REASON for that, but it wasnt because of stopping power... It was because of bread mold LoL!
Why did so many people carry them back in the day? It wasnt because YOU could ever have sopped me with one.. It was because ~I~ may have stopped me if you pulled one. There WHERE no antibiotics back in those days. If you shot me in the guts with one of those I knew damn well I was gonna die and I was gonna die a HORRIBLE death to boot. Thing is.. if I was a bad guy, I would have done it a WEEK or so.. At least a few days.. AFTER chopping you and your family apart with that ax. I would have died from the INFECTION. Today we HAVE good medicine... Criminals dont die a week later from infection, and they KNOW it. Todays we need STOPPING power for CC. It is no longer a matter of "scaring" they simply ARNT afraid because they KNOW chances are good they will survive a handgun, live a few months at the tax payer expense, and move on with the NEXT victim. Today it doesnt MATTER if he may or not die.. what matters is that he doesnt take ONE MORE STEP towards you or your family.
I live WAY out man.. and Im a hell of a lot more likely to run across rabid or feral dogs, garden robbing rabbits or pissed off copperheads then I ever am the odd meth head or moma bear... BUT, I pack a .44 because the odd meth head and moma bear DO exist.
When it comes to CC and Personal Protection, especially with a C&B, the key is to go BIG or go HOME... Usually in a body bag.
Just the personal opinion of a nut bar who actually DOES carry these things.. YMMV...
