+1 for the Crown Saver. I buy the 3” square white cotton patches and cut them in half. Feed the CS from the muzzle out the breech. Fold the 1+1/2” x 3” patch in half lengthwise. Center it on the CS loop and pull it out thru the muzzle. Uj

If you want to do it with stuff around the house, you can use weed wacker line. Just melt 1 end so its a small bulb that will hold a patch (or a cut up cotton t-shirt).
