For 6mm barrels, I favor a piercing type jag .22 CF, in front of a 44" coated .22 caliber Dewey rod running through a bore guide that fits the chamber and has a bushing on the rod that plugs into the back of the guide. For 133 with a barrel that does not have copper fouling issues, I would usually be confident for strings of over 30 rounds, assuming the loads were not low pressure, which gives a little more powder fouling. I like 1 3/8" square ordinary cotton flannel patches. My bore guides have a solvent port.
For the first patch I run a sloppy wet patch (Butch's) up and out. For several more, I short stroke, very short spending a lot of time in the throat, then up the bore, about a 3" stroke, paying close attention and exiting the muzzle in a normal manner, with a careful pull back.
By the time that I have run three or four that way, I am ready to brush. I use a reasonably fresh bronze brush, wet it with solvent and make end to end cycles carefully, paying strict attention so that I do not bow the rod , or pull the handle much off of the CL of the bore, about 20 cycles. Then I run three sloppy wet patches straight through, let it sit for 15 min. or so, and then run another and check the color. If there is a very light tent, I don't worry about it. Assuming that, I dry the bore and chamber, wipe off the muzzle, lightly grease the lugs, and put a little on the cocking cam. When you insert the bolt, hold the trigger and push it all the way forward, and hold it there as you turn the handle down. To put some grease on the seats. Every time you take a rod completely out of the barrel, wipe it with a paper towel, wadded up, and pull the brush through the wad when you are finished brushing. Don't lay rods or your bold on a concrete bench.
Added later: For CF .22 everything is the same except I use a much smaller patch. I make them small enough that they are not tight.
