Eldequello, You can shoot quite a few shots without swabbing. I don't havea lot of experience with all this, but most of my shooting has been with 460 gr conicals using 100-105 gr of Triple 7 ffg. I usually swab after about 10 shots. I start to feel the crud ring building at that point. Pushing the bullet down the barrel is so easy, shot after shot. I think once you start the bullet, the rifling/bullet have very little friction. Kind of like an ice skate sliding across the ice.

I imagine if I were shooting 70 gr of powder, I may not have to swab at all. Or maybe using a different powder.
