I’m using boretech eliminator and like it so far, but using it with Dewey rods that have brass jags gives false positives for copper fouling. Any recommendations for cleaning rods/jags that will prevent false positives? I’ve looked at the boretech rods, but they are to long at 36” (rather them be a little shorter), and I like the jags that you wrap the flannel patches around instead of poking through.
