What Bullets To Use Remington 870 How Often Do You Clean Your Gun?

How often do you clean your gun? - what bullets to use remington 870

I wonder how often they clean the world with their weapons. Usually cleaning the barrel, and ending with the recipient to take any time to hunt, and destroyed after each several times. Sometimes I clean my weapons, so I only shot a few rounds though. I only use non-corrosive FMJ or a panacea. Well, if I am to clean after each shot time, no matter how many rounds of fire? (I have a Ruger 10/22, SKS Norinco, and Remington 870 12 ga.)
