I know who this guy is lol@TheBigCountry @TylerN
His other least favorite is people using CLR haha! again he said they work but you need to be extra cautious about cleaning the cleaner out and protecting the barrel after.
I had typically always run 2 dry patches after cleaning, then 1 soaked in slip2000 and then 1 dry. Apparently that wasn't enough using it with BT. Of the things I had on hand he said just go back to Hoppes 9.
