What do you guys think of Barnes Cr-10
Wonderful stuff and the only commercial cleaner I would use.
I went through pretty much all the stuff a few years back. My criteria was removal of copper AND speed.
Many things got the job done but needed lots of elbow grease or time. Not my idea of fun.
Then I tried CR10 - Wow, heed the warning on the label. Do not leave in the bore for more then 15mins and use in well ventilated area.
Very strong ammonia content and was the only liq cleaner to 'mine' the copper out of my WWII specials.
I used CR10 behind EVERY commercial cleaner I could get at that time including the brands mentioned above and EVERY time I got out more copper and crap. Now I am the first to say that you don't need a spotless barrel to regain accuracy and most of my barrels are filthy but shoot great.
But this proved to me that all the cleaners I had available were not able to do a complete job.
Now CR10 is nice and pricey so I began looking for something that would do the same thing/same speed but cost peanuts.
I found GM top engine cleaner. Cheaper and does a wonderful job of getting rid of the carbon fouling (what is is designed to do) but my local dealership stopped carrying it so off I went again.
I tried a few other carbon cutters and they all seemed to work the same. Found a sale on a big jug of Kleenbore solvent and that has been what I have been using for a while.
Now onto a copper remover. Well we know ammonia is the most common active ingredient so I went looking for something strong.
I found janitorial grade ammonia - WARNING - this stuff is very strong and must be used outside. DO NOT LEAVE IN THE BORE FOR MORE THEN A MINUTE OR TWO.
Super strong, brutal stuff....and dirt cheap. PERFECT
This stuff removes copper right now. Wipe it in, wipe it out. No wait, no muss, no fuss. Dry patch it out, maybe a patch of light oil if in a high humidity area - good to store.
I can clean my factory rifles in a couple of minutes and my match barrels with a few patches. Fast, simple and cheap.
As a huge bonus, I find this ammonia solution cuts through carbon very well too. So I am now only using one solution for all my cleaning.
I have used this for a few years now and have dissected a couple of dead barrels just to see what the bore looked like.
All 6.5 Mystics (260AI) with 1500 to 1800rds. Bye bye throat and quite a lot of rifling downrange. ZERO carbon build up in the throat area. NO copper visible.
This is what I am using now and will continue to use it until the next best thing.
I found my stuff at ZEP janitorial supply place. I need to stop by and get another gallon. The last one cost me $16 and I have given away more then I have used.
Even if it now costs $25, there is enough solution there to clean thousands of barrels. Cleans fast so you don't need to use a bunch....
Good stuff.
