Not sure what you are referring to but I have recently adopted an easier method of cleaning all my ML, especially the one with a tang screw. I'll be doing this for 5-6 times then remove the barrel one time.
I have a small chunk of leather I put between the hammer and the nipple.
I use a regular 16.9 FL.OZ drinking water bottle. Put a few drops of Dawn dishwashing liquid in it. Fill bottle with the hottest tap water, not boiling water.
Lean the rifle so the barrel is muzzle up, hold a dry towel around the muzzle of the barrel with one hand and slowly pour the water in with the other until barrel is full. Let it sit there for 10-15 minutes. Remove the chunk of leather from the nipple and pour water out. You can do this a second time if you want but I found no benefit in doing so.
I follow up with a rinsing of pure warm water, no soap.
Then I remove the nipple and run dry patches down the barrel to soak up any water until they come out dry.
Most of the time I use compressed air to blow down through the flash hole. That will remove any crud that may be trapped inside. Then run another dry patch down the barrel to remove any of the crud and water that may have been in the flash hole and pushed into the barrel by the compressed air.
Clean the nipple with a toothbrush and reinstall with a dab of oil on the threads.
Follow up with whatever cleaning solvent/bore protector you wish to use. Ballistol, TC13, or whatever.
Lastly, I always clean around the nipple area and the hammer then oil a patch and run down the barrel before putting the gun away, as well as apply a thin coat of oil on all exterior parts. Then I wipe down the wood.
With that said, what I personally do is first I remove the barrel, or on every 5-6 cleaning when the barrel is removed, I apply a heavy coat of Bore Butter on the underside of the barrel and in the stock cutout for the barrel. This forms somewhat of a seal that is easily removed by wiping. Then reapply a new coat and reinstall the barrel. I do this to keep any water from getting between the two and perhaps allowing rust to form. However, its easy not to spill any water while performing this process if you go slow. Even if you do, the towel should catch it before it can run down under the barrel and/or onto the wood.
I simply do not see why the barrel should be removed every time I clean my ML. But that's just me.
This guy uses the same basic process.
