I've noticed that shooting a lot of rounds in a session leaves a ring of
grunge on the breech face where the cartridge's headstamp rests. Most
of the fouling is easily removed, but on my stainless steel pistols
there remains a ring-shaped stain that's almost impossible to get off.
(For all I know, this also occurs on blued pistols but just isn't
noticable.)
Repeated swabbing with Hoppe's doesn't help, nor does vigorous brushing
with a nylon brush. I'm reluctant to bring a bronze brush to bear after
my first attempt left some scratches on the face. I've considered
preventative measures, such as a very light coating of oil, but I doubt
its efficacy and the potential drawbacks (penetrating the primer of a
chambered round or gumming up the firing pin channel) are considerable.
Does anyone have a sure-fire way of removing heat- and pressure-embedded
headstamp marks from a stainless steel breech face?
