Cleaning bore ...? Solvents ?

Lawrence, I have heard of many people using a #9/Kroil mix, I have never tried it. What caused you to try it and have you tried other solvents in a comparison test. I'm not looking to bust your balls, i'm looking for a good reason to try it. I guess maybe the thing to do is try it myself? Currently I use shooters choice for carbon and KG-12 for copper. The last barrel I broke in was terrible and i did compare several different copper removers, KG-12 seemed to be the best (Quickest) for removing copper. They all worked but KG-12 got the job done much faster, I tried several and inspected with a borescope. Never really did a carbon cleaner test.

Mike,

The Hoppe's #9/Kroil mixture came about while I was using moly coated bullets. I found it worked well knocking loose carbon fouling and have stayed with it to this day. Being a petroleum based solvent it makes the use of bronze bore brushes much easier than water based solvents. I have tried many other solvents but have not found any that do the job on carbon any better than Hoppe's #9/Kroil when used with a bronze bore brush. My usual routine is to run two wet patches down the bore followed by five to ten passes with a bore brush to remove the loose carbon fouling. Dry patch the bore then move on to Bore Tech Eliminator to remove the jacket fouling. Removing the jacket fouling takes longer than removing the carbon fouling. Eventually burnt on carbon fouling deposits in the bore and a carbon ring at the chamber mouth will form which must be removed with abrasives. Let me know if there is anything else needing clarification.

Thanks Lawrence, What mixture do you use? 60/40 60 Hoppes, 40 Kroil? I'm going to give it a try? Have you ever head of guys using Shooters choice instead of Hoppes, I have a bunch of Shooters Choice?

Hey Mike,

I kind of eyeball the mixture, but its more like 80/20 Hoppe's #9 to Kroil. If I am not mistaken Shooters Choice is a petroleum based solvent and therefore should be compatible with Kroil (they should mix well and not create negative side effects). Let us know how it turns out if you decide to give it a try.

Years ago, when I first heard of adding Kroil to #9, I did a comparison and found that it was obviously better than #9 alone, for powder fouling. About that time, I told an older friend, who had been using #9 for powder fouling for a long time, but as is the usual for him, he was skeptical, so I told him to bring a small bottle about half full of #9 the next time he was at my house, and I added enough Kroil to make a 2-1 mixture. He tried it, and agreed that it worked better. After that I ordered a gallon of Kroil, and split it between two friends and myself. Later, when I got my first 6PPC, and started off shooting 133 in it, I found that because that powder burned so clean, that I could simply use a single bore cleaner and get the job done. I settled on Butch's Bore Shine for this, and although at one point thought that Lyman, had changed the formula, because of the color of the patches, continued to use it, with satisfactory results for a long time. Now that I am trying some of the new powders that have been developed, that are slightly dirtier, I am experimenting once more with bore solvents, and cleaning procedures, so that I do not have an accumulation of powder fouling turn into a hard carbon issue, that requires an abrasive to solve. The jury is still out as to whether there is anything out there that can accomplish this. We shall see. Perhaps I need to try the old standby, Kroil and #9, and go back to a two solvent cleaning procedure.
