When I tested Butches, wipeout, Barner CR10, Sweets, Hoppes, JB, etc a few years back, it was for both match and factory barrels.
My objective is speed. The only time I have to clean is at the range BEFORE I come home so waiting for hours to have a solvent work was not in my cards. The number of shots could be a few to alot depending on the rifles end use.
Since I saw that powder was something that many solvents handled well, the next chore was getting rid of the copper. Hearing so many glowing reports on Butches and other cleaners, I decided to give them a try and see what they would do.
What I found was that wipeout was very slow - no matter how well it might work, it would never work for the time frame I was allowed. A few minutes per rifle....
Sweets was much better but still slow.
Butches did a nice job on the powder but didn't do much for copper at all. Used in several barrels, I cleaned till patches were lily white. Then cleaned a bit more just to ensure that I was giving the cleaner the best chance to work.
Putting another wet patch of either Sweets or Barnes immediately showed blue. It would take some patches to remove the remaining copper. Since this was repeated with various barrels that would copper foul, Butches was not for me.
Hoppes Copper shared a similar fate. Just wouldn't cut the copper.
When I got to Barnes, I found what I was looking for. I know some are concerned about strong ammonia in their solvents but I have not found any issues with my barrels. So I just wipe this stuff in (outside only), and wipe out the fouling - powder and copper - all in one solution.
Definitely not something you want to leave in your barrel for any length of time which is exactly why I like it. It cleans as fast as I can run wet patches down the bore. When the patches show no copper, no other solvent can extract more so it is pretty much gone as far as I am concerned.
JB does a similar job but will not get into the rough spots found on factory barrels.
Now I have found a system that works even better and is a whole lot cheaper. I use a powder solvent made by Kleen bore. Any quality product will work. The Kleen bore was on sale at the time. GM top engine cleaner also works well.
When the patches turn a light grey, I switch to janitorial grade ammonia. Pretty much as concentrated as you can get without a license. This is not the stuff you find at the grocery store (that stuff doesn't do much by the way) but at stores like Zep.
USE OUTSIDE ONLY.
This stuff dissolves copper like magic. If it is in the bore, it is coming out without scrubbing. You just need some snug fitting patches. Wipe in, wipe out. A couple of dry patches to ensure nothing is left and you have a clean bore. Of course, a bit of preservative will be a good thing if facing rust. Takes only a few minutes to clean my rifles.
One of the biggest surprise when using this stuff is that the first patch or two is also coal black. The only thing I can figure is that this is getting out that hardened crud in the throat area. AWESOME. I have autopsied a few barrel that was cleaned this way to see if there was caked in fouling in the throat and have found none. No copper, no powder, no nothing.
I am almost at the point where I will only use this conc ammonia solution to clean my barrels. Why not, it is getting rid of all the crud?
So I have a method that works for ME. It is very fast, does not require brush scrubbing unless I am dealing with something like a surplus pitted barrel. Dirt cheap and readily available.
I have shared this ammonia with other shooters 'brave' enough to use it and they have also been thrilled with the results. For those concerned with ammonia, this is the worse possible stuff to use.
So use whatever makes you happy. No one method is particularly better then another. But there are different methods and learning about pro's and cons can sometimes open new doors to make a task easier.
By the way, I have used barrels from Gaillard, Douglas, Kreiger, Shilen, Brux, and a few others picked up at gunshows. Any of these top quality and lapped barrels have copper fouled very little if any.
My F class barrels usually fire 45 to 60rds before cleaning and rarely is copper an issue. My present Shilen Select Match in 223 has gone about 100rds then cleaned with only a bit of powder fouling and no copper. Butches would work well in these barrels for sure.
YMMV.
