I tried posting this question to a general questions forum on Gunco, but got no response, then I saw this forum and decided to try here. My question (I'm relatively new here) involves my desire to shoot my AK47 (7.62) subsonic. Would it be more practical to reload the 7.62X39mm round to subsonic levels using larger bullets and very short burning rate powder OR: would it make more sense to convert the rifle to 9mmX39mm? I have tried to find reloading data for the 7.62X39 round, but it seems there isn't anything out there about this. Does anyone on this forum have any knowledge about subsonic reloads for the AK in 7.62? Or does the caliber conversion make more sense and if so, where do I go to find info on that conversion? Thanks for your time and consideration.
