Why this site exists

We have learned that there is a serious lack of safe and legal 37mm supplies that exist for reloading your own specialty rounds. Dark Technology has brought various types of 37mm files from around the web to life using 3d printer technology. All rounds on this site are for reloading yourself using a 209 shotshell primer, a powder charge and your imagination. This is a work in progress and will be updated continuously. Have fun, stay safe and behave.
