I use a loose fitting patch soaked with Rem Oil and pass it through the barrel about 5 times….let is set a while, then dry with patches, plug the muzzle with a tight patch and basically fill the barrel with the Wipeout foam, let it soak overnight, then clean with tight fitting patches until they are only slightly gray. I clean after every two matches, about 100 or so rounds fired. Seems to work for me.
