I had my 1st chainfire a few months ago with my ROA. I use lubed wads and the #11 caps work fine on most of my cylinders, I have a few aftermarket cylinders and one seems to prefer #10's. Mine was definitely from the cap side as I found the #11 cap unfired on the table I was shooting from after the double shot. I've since replaced the nipples and use #11 on all my cylinders. Welcome to the chainfire club, it only took me 25yrs to join, and I hope not to revisit.
