I too use the patchworm. It is a great cleaning tool. I use it for light cleaning, running patches through with solvent, in between regular heavy cleanings with a rod and jag or brush. I have found that I can keep the barrel cleaner longer without a lot of harsh cleaning with rods, jags and brushes. It does not take the place of a cleaning rod, but provides a low impact method of removing minor barrel fowling. If you like a clean barrel, but cringe when using a rod and brush, then the patchworm may be for you.
