l need some info on this RCBS trim pro-3 cutter head does it use 7/16 X 20 tread? l have a chance to buy one at a very good price l need to know what the tread size is, l have a spare trimmer looks like a Forster but it's not it has no name on it, it has a 7/16-20 female tread that l would mount the RCBS cutter head on it if the RCBS cutter had had a 7/16x20 male tread.
