If you are going to swab your bore before shooting, that is fine. I usually do not. But what I do that you didn't mention is when I fire a couple caps to be sure the nipple is dry, I run a patch down the bore on my cleaning jag, and keep it down there as I fire off the caps. This does two things: 1. keeps the bore from getting fouled and 2. a visual inspection of the patch when removed proves that the flame is getting into the breech.
