RX for Frosted Lands?

there are ways to remove rust/corrosion from a barrel using electrolosis or electrolitic action or what ever the vendors call it. its essentially hooking a stainless steel rod up to a batery charger and sliding it down the barrel center and hooking the battery charger up to the rifle. essentially you are plating the stainless steel rod with rust from the rusted barrel. Called lots of things by many vendors. very effective too and well docummented process on you tube.

advantages are

it removes the rust/corrosion and not the good metal.

it leaves a nice etched kind of surface that you can fill up with moly grease and if you heat up the barrel carefully the moly will penetrate the opened pores of the metal and to a limited extent prevent additional corrosion but will provide a lubed surface to help the bullet travel down the barrel with less resistance and less wear on the barrel. you can then experiment with using less powder which will itself reduce errosion at the chamber end as well. it will not return "metford" rifling to grooved rifleing" if you know what i mean.

Polishing the barrel to remove corrosion is a limited proposition in and of itself. I know I mentioned using a lubed based valve grinding compound but it and polishing remove metal as well as corrosion. they work to smooth the surface but they remove the good with the bad. etching process''s work very well too. Brownells and others sell kits to etch barels,look at thier website but also check out you tube to get an idea of the theory and practice in action. its an amazingly simple process.
