You need to clean the copper out sometime but not nearly
as often as a bolt gun.

If I can going to the range this weekend and next weekend,
then I probably won't clean the copper out but will take
the carbon out and oil it.

I do clean all the guns at the end of each year and that
is strip all the powder AND copper out at the end of
each year to bare metal, then plenty of oil.

Just be aware, his comment of cleaning the powder out,
the powder / copper tends to go in layers. Hence why I suggest alternating when doing a thorough clean.

Hope that helps.

Graeme Wright was using it to clean his doubles.
