Iam in the process of breaking in a barrel. I shoot seven rounds last Sunday. And used sweets. 7 69 .I let it sit in my barrel 15 minutes then swabed the barrel. Then patched it out till it looked fairly clean. Then shot and repeated till I had no time left that day .this being a family man I kinda tough when u want out pf the house. My girls keep calling wanting me to come home and spend time with them. OK back to this. I got in my order from miday with wipeout and tried it after 6 hours no blue liquid can out of the barrel. Is the liquid support to turn blue when using it. With the sweets there was lots of blue. But not with the wipeout. What do u guys think. It had ten rounds down the barrel.?
