None of my local retailers stock anything for a 20 cal. I have ordered online 3 times to get a good cleaning rod and they are so wishy-washy on what youll get. I have yet to receive a combination that will work together, the rods are either too big for the bore, right size but male threaded? What gives? I got a nice set of brushes yesterday but they are a smaller than normal female thread and the package don't state the thread size and pitch? It cant be this hard...
