Use Wash Bottles to Apply Solvents
Using wet patches or wet brushes is an inefficient way to really saturate the tight bores of 17s, 20s, and 22s. Even with a cotton bore mop, most of the solvent will be squeezed out before it gets to the end of the bore, where most copper fouling occurs. Here’s a simple solution. Get a small plastic “wash bottle” and fill it with your preferred solvent. Then stick the tapered nozzle right in the chamber. The tapered end will press fit in the throat, sealing off the chamber. With the barrel slightly nose-down, give the bottle a couple good squirts until the solvent mists out the muzzle. In just a few seconds, this will put more solvent in the bore than a half-dozen wet patches. Alternatively, plug the chamber and squirt solvent in from the muzzle. It’s also much easier to saturate a bore brush (without spilling solvent on your stock), by using the wash bottle. You can get these bottles from USPlastic.com or lab supply stores.
