Western Powder Montana Extreme Copper Killer- 20 Oz
The Western Powders ballistics lab fires tens of thousands of rounds a year and spends a considerable amount of time cleaning barrels. Our engineers created Copper Killer for use in the lab to speed the cleaning process and bring test barrels back into specification after extended shooting sessions. Now our lab’s industrial-strength product is the top rated copper remover on the market. Its unique buffering solution is completely barrel safe and contains no acids, amines or chlorides. Copper Killer is simply the best copper removing agent available for high volume shooters.
