So with all this talk about 777-what is the best way to clean the barrel?

Do you use soap and water? Or something else like Lyman or some
other brand of solvent..I have only tried the 777 in my cartridge rifles..

Even though I have lots of Goex on hand,I kind of like the idea of the
pellets.....What is the Goex Penntical like...I aint no good at spelling..
