If you are a wiper, these things are the cats meow. They are quick and thorough and work equally well with greasers or patched.
If you do decide to go with them, my advice would be order 2 kits for your caliber, and a box of the felts.
I soaked them in the napaoil/water solution and pushed them thru with an arsenal patch on the tip of a delrin rod.
Just be sure to put your patch pan well out in front of the muzzle as those buggers do gain some velocity and have a pretty good trajectory as they clear the muzzle.
A wise man can always be found alone. A weak man can always be found in a crowd.
