Have a gp100 that would lead worse than a Flint MI water pipe and shot patterns instead of groups. Throats were tight and could not push a lead bullet thru them. Sent the cylinder off to fellow member DougGuy so he could work his magic.
While that was getting done I did a full polish on the internals installed lighter wolff springs and shimmed the hammer. Got it all back together and it is a night and day difference. Before it would lead bad after just 30 rounds. Using a lewis lead remover I could pull out slivers of lead dam near enough to cast another bullet. Now it is clean as can be after 100 rounds.
Accuracy is greatly improved. At first I thought there were still flyers but a short walk to the target revealed many rounds touching. Also seems to run cleaner. Before there was heavy fouling on the cylinder face and now it is a lot less.
I highly recommend Doug and will vouch for his work. Fair price and quick turn around time.
