I used Bore Butter because these were the cleaning patches I had with me at in my MZ shooting kit I brought to the range the first day I tried me some BH209 - that's all. I do know that i put two shots into an inch at 150 yds after cleaning, Patches were pretty dirty after the first 7 shots. I'm not a big fan of having bottles of liquid cleaner at the range. I also have some T/C T17 saturated cleaning patches that are made for cleaning 777 and BH209,

So . . . . how many shots do you guys take at the range before you clean the barrel? I based my cleaning on when I noticed a change in seating of the saboted bullets.
