All Proof-Positive Patch Jags feature a proprietary alloy that is as soft as brass and100% barrel safe. I copied this from Bore Tech's website. Even though I like their cleaners I do not trust them with their jags. Sorry. You let me know what that proprietary alloy is, then I will decide if it is safe to use in my firearms. Anybody can make the claim that it is barrel safe. Until then, I am sticking to the brass jags, or I might consider the aluminum jags.
