Wipeout, Gunslick foam, the whole KG system, Shooters Choice/Kroil mix, Montana Extreme, BBS, warthog1134, whatever I feel like picking up out of my cleaning kit.
What's really surprised me lately is filling up the bore with the gunslick foam and letting it sit for about 30 minutes. Take a patch and wrap it over a brush. Stroke the bore about 20 times. Replace brush with jag. Push about 2 dry patches. Push a new patch soaked with any regular solvent....I mostly use the choice/kroil mix as it is in a bottle always handy on my cleaning vice. Push a second wet one down. By this time the second one comes out clean. Then dry patch.
I've double checked this in a couple of rifles in the last 2 weeks and rebrushed them with another solvent thinking the patches would come out black but they didn't.
