I'm in the process of setting up my Dillon RL550 for 300 Blackout. Since the parent case is 5.56, I can use all of the 223 stuff except the powder funnel. Dillon recommends the AK funnel, which Dillon does not list as a separate part. I assume it is basically an extended "B" funnel so I am going to try to turn one on my lathe. Does someone have a picture of an "AK" funnel that they would care to share ? I would settle for the length of the funnel since I plan to duplicate the "B" funnel as much as possible. Thanks !
