I clamp my cleaned rifle in a padded vice, barrel straight down. I tape a shotgun hull to the muzzle to catch runoff product. I dip a loose fitting patch, use a slotted tip, run it back and forth as I advance it down the barrel, chamber to bore. I do that several times. I turn the gun upside down, muzzle up, block the chamber with a rag and repeat the process.
Prep is the secret. I use a Hawkeye borescope to make sure the bore is absolutely clean before starting the process.
I usually let DBC dry for a few days or until I get to the range. Sometimes it may be a week or two.
After a few shoot and clean cycles, cleaning seems to get even easier. I have premium barrels, Hart, Brux, Kreiger, etc. that just about don't foul even after a number of rounds. And, that's checking with the Hawkeye. I swap out powder residue with Wipe Out, take a peek with the scope and I'm good to go.
Great product.

Pretty good idea,
especially for a coonass!!!
