I was just reading the thred on teflon patches they were saying the teflon patch is a dry patch and won't foul you powder load, well that got me to thinking :hmm: what about a dry grafite covered patch. Has enyone ever tryied this. Grafite is carbon based ,or mabey the grafite spray that they use for coating your moulds for casting boolits( no petrolim as a carrier). Just a thought, mabey get some marbles moving. Dave T. :winking:
