I've had pretty good luck, but then I'm cleaning the bore and checking what I did after every other pass. I bought a 1894 Remington F grade " trap gun " for a good price because the right barrel was only IC choke. By jug choking it I took it to a Mod. But that takes quite a bit longer because the reamer is put to the proper place then adjusted tight against the barrel, reamed, adjusted back down so it can be removed and cleaned. Then clean the bore of cutting oil so the mic can be used without gumming it up with oil. Because the reamer is in the barrel when adjusted tight you can only get a thou or two. Takes awhile, but if there's enough wall thickness, choke can be put back in.
