I'm always a sucker for cleaning supplies, and when I saw a bulletin on 6mmBr, I thought WTH. Ordered some of these for .22, .243, and .308. Won't have a chance to use them as I cleaned every thing when the weather turned bad last winter. Most of my paper punchers need a dirty bore to settle down before shooting for a group.
