Its really not too bad, though. The only blanks that have "wads" are the M1909 Goverment issue blanks, (paper plug with red sealant). The bulk of this is burned up by the time it reaches the muzzle. Removing and blowing out the BFA after a couple of hundred shots is enough to keep the gun running. I've fired literally thousand of blanks in M1s and this routine cleaning is really all that is needed. What does occur is that as carbon builds up on the BFA, you will get more violent recoil and over time, damaged op rods. Most of today's blanks are crimped and have not plugs at all.
