My second generation benjamin marauder .25 is about two years old now. From the time I've own this gun, I've only cleaned the barrel twice. The first time I got the gun, I ran some patches through the barrel to get out anything that might be in there. I cleaned the barrel the second time only because it's been so long since I done anything to the barrel even though I didn't see any loss in accuracy. Since the second cleaning I haven't touched it because I haven't seen any lost in accuracy. It will shot half inch groups at fifty yards all day. My disco in .22 is a different story. After about 200 pellets, I have to sit down and clean the barrel. I've never own a .177 pcp but I did start with a .177 break barrel springer and from what I can remember I use to clean the barrel often. Maybe once a month. My question is does the larger the caliber equal less barrel cleaning? I have never own or shot a .30 caliber or bigger before so I wouldn't know if a larger gun then mine requires less barrel cleaning. Logically, from the guns I've own, I would say a .50 requires less cleaning then a .45, a .45 requires less cleaning then a .30, and so on.
