Having just purchased a Teslong bore snake and then using it on every barrel I had (13) I found that I wasn't getting the carbon out as well as I thought I was. So I broke out the ISSO and the JB Bore Paste and scrubbed the carbon out pretty darn quickly. Way more quickly than a brush and Hoppes did. An old Savage 112 BVSS in 220 Swift was carbon city from dog town safaris. Heat checked yes from maybe 700 rnds but not a bad throat overall. It was harder to get clean from copper and carbon fouling than all the others. I used Shooters Choice and also Sweets. The JB paste and maybe to a lesser degree ISSO cleaned faster than the chemical brews. What did you all discover about your cleaning routine after you could see the results better?
