Ok, so I think I have a handle on this but still don't quite understand.
The general advice I have read is to always clean from the breech end if possible in which case you would use a bore guide to protect the chamber. But, the crown of the barrel is supposed to be the part that you are really supposed to worry about so what do you do to protect it after you push out a jag/brush? Is it ok to just pull a brass jag back through or do you guys unthread it first? It seems pulling the jag backwards could conceivably hit the crown as well.
