I think I remember reading something from uvhalo about rifle on rifle action. He said something along the lines of pieces of shell leaving residue along the grooves. Not enough to distort the in flight pattern of solo rounds. After a hundred or so shots, the rifled barrel has to be swabbed to remove fin particles.
