I've been mixing and using Ed's Red for over 20 years. I wouldn't use anything else. The first time I used it, I took the advise of another and started cleaning a gun that I thought was already clean. At that time I had a model 19 S&W revolver that I'd been shooting lead bullets out of. I was 100% sure it was clean. I ran a sloppy wet patch of ER down the bore, let it sit for a couple minutes than ran a dry patch down and many thin spiral shaped strips of lead came out of the bore along with plenty more carbon fouling.
I recommend you do the same, start with a gun you think is clean and clean it again with Ed's Red. I'm sure you will be a convert too...
