Here's another issue to consider when using CCI shotshells for self defense, or any other reason. Last summer I began loading one in the first chamber of my Taurus M85UL in response to a rash of copperheads near the house. After having to use them once, I began loading them in the first two. When I had the occasion to use it again, the first shot did not do the job well enough so I attempted to fire again, but the cylinder wouldn't turn. The recoil had caused the plastic shotshell cap to back out enough to jam the gun. The following day I fired off a few target rounds with a shotshell in the cylinder and found the cap to back out far enough to jam the cylinder more often than not. I would suggest you examine this problem with your own gun before you decide to use them for any reason. As for me, I still will load one, and only one, when I consider it may be called upon, but I don't consider it a valid choice for self defense.
