Yes the paper acts as the patch, no need to add a separate patch. I dip the ball end of the cartridge in a mix of beeswax and parafin to give it some lube when loading. You are correct in biting off the end. At some military type shoots that I have been at, we bit off the end, primed the pan (would not recommend this except that the exercise we were participating in it was proper), poured the remainder of the powder into the barrel. Next I flipped the cartridge over, pushed it in to the top of the ball, tore off the paper and then rammed home. For more speed, don't flip it over, just ram it home, paper and all. You will be surprised at how much accuracy you can using the paper patched ball. Oh, one thing I would recommend, the fouling in the barrel will build up quickly because you are not using a cloth patch, so I would use an undersized ball in the cartridge to aid in loading. We were doing a speed/timed shoot and there was no time to swab between shots. Kinda long winded, but hope this helps some.
