RE: Montana Extreme
I also am using Montana Bore Conditioner and as soon as I clean the factory preservative out of the barrel on my brand new Endeavor I put the MBC in. I have been satisfied that it is the best I have tried. I do not recommend there standard Bore cleaner for muzzle loaders,it did not work well with Blackhorn or Pyrodex but I intend to try the Cowboy bore cleaner that Dave likes first chance I get.
