"The Tipton 20 Caliber Ultra Cleaning Jag features a patent-pending technology that covers the surface of a traditional push-type jag with solvent-proof material keeping aggressive modern bore solvents from creating false blue stains that normally indicate copper fouling. Before Ultra Jags these false blue stains caused users to over-clean their barrels - and that's been proven to destroy accuracy over time. Nickel/Brass Take a modern bore solvent and squirt it on a brass cleaning jag. The liquid will turn blue as it drips off the jag - it's working so fast it starts to dissolve your cleaning jag in front of your eyes! If you're following conventional wisdom ""clean until you get a clear patch"" you might be in for a long day of cleaning!
When you use Ultra Jags you'll get better faster cleaning results because you'll know you're getting blue stains from copper fouling from your barrel and not from the surface of your jag. In addition you will increase the life of your jag by protecting the jags brass core from the aggressive modern solvents with the nickel-plated coating and increase the life of your barrel by not over-cleaning.
