Well what ever people use is their business.

I personally find it just as easy to carry a couple strips of cloth. These strips are three feet long and two inches wide. I have them pre lubed when I hunt. I simple soak them in moosemilk, squeeze the lube out with my hands, and lay them on an old window screen. The liquid lube dries out, but the oil from the lube stays in the cloth. All I have to do is fold that up and put it in a zip lock bag. I can pull the whole strip, lay an end over the muzzle, short start a ball into it, cut the strip away with a knife, and simply put the strip back into the zip lock baggie.

So I guess I would have no interest in your invention.
