The initial patch lube / treatment will be a mixture of beeswax, rabbit kidney fat, and SIMICHROME polish. I'll be keeping my eye on the crown,and certainly measuring it, as dialing the new (as yet to be built) sights in. Cannot anticipate anything much happening, ....bore condition wise, than the gradual disappearance of a fairly uniform brown internal "patina".
Can't feature this one being ANYTHING but a shooting fool.
