The rods for 0.22 cal, that I own, all rub against the ejector which forces the rod against the chamber. The rod with the smallest diameter does it too and measures 0.185" It is a P-H with the plastic stripped off. The advice that I have seen is to get a Possum Hollow guide and a rod for a 0.204 but does anyone know what the diameter of the 204 rod is? If it is smaller than my 0.185" "modified" P-H, I would get one.
Suggestions, recommendations and advice are welcome
