Depends a lot upon the individual barrel and cartridge. I won't tell you how often to clean it, but I will say I often run a boresnake through and let it go a while. Just enough to get out any large powder deposits lying in there. You don't want to wait so long that the grooves  fill with copper. This will degrade accuracy immediately. Eventually I give it a real cleaning. Over cleaning has sapped the life out of many a barrel, IMO....
