On another ammunition related fourm, there is a question about why some blank cartridges have wood “bullets” in them. I say that they are there solely to aid in feeding, as they replicate the profile of a standard cartridge. Secondary to this, the design facilitates the reuse of fired cases to make blanks. The opposing opinion is that the wood “bullet” is there to create back-pressure to operate recoil operated machineguns such as the MG 08/15, etc… and that no Blank Firing Adaptor is needed. I say the light weight of the wood “bullet” is insufficient to do this and a BFA/shredder is needed to operate the weapon. What say ye?
