For many many years I have used Hoppe's cleaning patches. I buy them in bulk from Midway. These sythetic patches always worked very well for me. The feature I like about them is that they don't shread / come apart or leave threads in the action or barrel. Alway worked great for me.
I recently order some more from Miday and it appears that they changed the design to a weaved cotton fabric which shreads to pieces when used with a pointed jag. Garbage.
Good job Hoppe's; you made something that worked and made it useless. My vent of the year.
