I couldn't find the answer,so apologies for posting again.
Basically I have two parker hale rods,
The grey 243 cal male fit, and yellow 30 cal female fit.
I'm looking for a set of nylon brushes for both and what ever adapter they both might require.
I think the pro shot series with male fit will fit the female rod, but the adapters all seem to be female-female in 30 cal.
