I know a lot of people fire a couple caps before loading, I don't. I usually clean the barrel free of oil with an alchohol patch, then I use a dry patch. Then I put my clean dry breech plug in and then I load.
I do not pull my breech plug between shots, I have never seen the need. I just swab the barrel with an alchohol patch and then a dry patch before loading.
When shooting conicals in my White I do not swab between shots until after several shots.
