A very interesting story about chrome rifle bores,thanks for sharing. Its funny but now days most of us associate chromed barrels with chinese rifles like the SKS. I don't know if any of our modern sport rifles manufacturers use chrome bores. My understanding about SKS bores is that they are highly resistant to corrosion.
On a slighly related topic I found a video on the net showing the use of a non electrical conducting "arbor" or " twisted core" with wires twisted along it. It is inserted in a barrel blank and electricity applied and it erodes the bore beside the twisted(spiral) electrodes to create etched rifling in the barrel. AN interesting idea, ever heard of this before?
