I seriously have my doubts that you can completely remove moly from the bore in a few minutes.
There is a big anti moly movement.

Moly destroys your barrel by attracting and trapping water in the barrel causing severe pitting.
Even if you live in a dry climate, temperature changes experienced during the hunting season (gun inside warm house - gun outside in the cold) causes the metal to sweat.
My barrel was destroyed by pitting after only 154 rounds 40 of which were moly coated (fail safe). I had cleaned every 10-20 rounds with Hoppes9 and Shooters Choice, both good cleaners, with the patch and brush method. It didn't get it out.
Moly is EXTREMELY hard to get out. Plug the barrel and soak with Kroil overnight. Then scrub with a mix of JB-Bore Compound and Kroil for 5-20 short stroke technique passes. USE A BORE GUIDE, quality rod and jag, and be careful around the crown (don't bang the heck out of it). Finish with a solvent of choice and good oil. Hoppes9 or Shooters Choice mops out the JB well. If you choose, you can use something a little stronger like Montana Extreme for a final solvent pass. Extreme copper solvents like Sweets 7.62 although are great at removing copper are probably not necessary with this cleaning process as the copper should have been mechanically removed by the JB/Kroil mix.
A moly conditioned barrel will not shoot Std. copper bullets accurately (relative term).
Stainless barrels are effeted too.
This does not apply to "Lubalox" (found on Win. ballistic tip) or the Barnes coatings. However, I still advise caution.
Over the last several months I have poured many hours of extensive research into this issue. I have spoken with nearly every manufacturer in the industry, and read every publication I could find. Many of the high end manufacturers made comments such as these, "I would never run moly coated bullets through my guns," "Not in a million years would I use moly coated bullets," "moly conditioned barrels shoot std copper bullets very poorly," " moly is nearly impossible to remove." The manufacturers that didn't make a derogatory comment made one something like this, "we have no comment." Winchester refused to comment on several e-mails I sent addressing this issue, but replied to every other product question I submitted (Hmm). The most telling quote was "moly is something we all got caught up in way too fast, before any real world data could be collected, and we are all paying the price for it now." Moly does have some good properties, however I do not believe they justify the risk.

I have recently had misgivings about shooting moly bullets, and it seems there is growing evidence that these coatings should be avoided. I first had some indication that moly may contribute to bore corrosion in normal chrome-molybednum rifle barrels, when I saw "Varmint Al's" little unscientific test on his web page. He put some moly on a barrel surface, and left it for 24 hrs in a humid state. The barrel surface was slightly etched after only 24 hrs.
Now even more troublesome info is surfacing. If you contact Sinclair International to order something ask about their current disposition towards shooting moly or Danzac coated bullets. ( Sinclair is a leading precision shooters' suply store). It is notable that Sinclair sells moly coating products, as well as the Danzac coatings from Kincaid, Inc. At the present time Sinclair is advising people that they are not shooting moly or Danzac anymore in their own rifles, and are waiting for further info on the risks.
In the new shooting book written by Sinclair and Gravatt (who run Sinclair Int'l), there is a section on moly coating methods, etc. They say in their book that they cannot recommend using any bullet coatings at this time, and it is quite possible that moly will prove to be only the first generation of bullet coatings. They also relate some of the problems observed with moly use. The most significant and worrisome is that if moly is not completely cleaned out of a bore it builds up on itself....and....that a form of pitting and erosion has been observed underneath moly in *stainless steel* rifle barrels, that is unlike any pitting they have ever previously observed in this type of barrel.
For those who haven't shot moly bullets yet, be aware that it is nearly impossible to completely remove it from your barrel. You can get most of it with strong solvents, but bore paste (USP, JB's) will also be required to get nearly all of it out. It is alot of work. If you have already used moly, it is very important that it be removed as best you can after shooting. Do not put up guns which have been shot with moly, before you have given them a very thorough cleaning.
The guys I have talked to at Sinclair are now shooting plain old uncoated bullets, and being very careful to clean all the copper fouling out.
