Actually, it sounds like a common-sense way to clean up a pitted old .311" bore and help it shoot well again, but these days if you can find someone who will do the work at all, it winds up costing more than buying a new barrel or an entirely new gun. As far as 7.62x54R brass being expensive, you can buy reloadable ammunition for $1/round from quite a few different places, so it's not bad at all. In fact, many wildcats use much more difficult to find and expensive brass than these.
