God, I hope you're right. ;-) I definitely went beyond half a tin. I think I went beyond a full tin. Way beyond, I'm afraid.
Does it make sense if I think (read: hope) that the effect of a dirty barrel may not be immediately noticeable at 40 meters, and progressively increases beyond that distance?
cheers, and thanks!
