I don't understand your question. Is this a trick question? You put a patch on the end of a rod with a jag, you put a little No.13 or the windex/alcohol mixture, or whatever is your choice. You insert it in the barrel, and in fast short strokes, you push to the bottom, until you hit the "thingy", you pull out, And follow up with two clean patches.

The powerstem was amazingly clean believe it or not. I was sceptical too. But was shocked how much cleaner it burned. No crazy crud ring cause it disperses the primer flame a tad. A 209 is just way too powerful, and I concurr with some writers that it lifts you charge and sabot off before a good ignition occurs.

Now with all that said, I plan on trying the other breech plug and playing with some other lower power loads. What can I say, I like to play and experiment.
