right, well, may as well chuck a grenade into this discussion, ahem!
there are some members (like me) who never clean a barrel-ever, there are some however, who clean their barrels regularly, be it one tin or two tins of pellets, or three months, whatever, although, I note our moderator himself (yes you BBF) said `MOST` -not- me or we, so, it seems you`ll have to find your own guns sweet spot `tween ammo, power, weather & hold (it can be a complicated old game this y`know!) then see if your accuracy drops off at some point & decide if its your (dirty?) barrel, hold, pellet batch, grey socks (that day) blue moon on a monday

or whatever, good luck
