RE: Using the Montana X-treme products
Breechplug I am going to guess you are fine. As for that nylon brush, I never used one except in cleaning my revolvers. Do they knock fouling out of the bore good? Maybe later on, you want to get a brass brush. I really am kind of wondering how your rifles will act, since they are new.
Also when I shoot this big .58 next time, I want to see if the first shot moves into the rest of the shots. It was so sunny today, I had to take a black magic marker and darken the front sight. As it glared when looking into the shadows of the woods. But when I turned it black, it stuck out like a sore thumb. Some solvent took the black off at the end of the day.
