hey guys i'm looking at building a STEN type SMG, but in a .22LR as the rounds are easier to get than 9mm. if effective range is 50m i'll be happy. problem is, the .22 has a rimmed casing, just wondering how well it will auto mag feed, and will it have enough recoil to recock the STEN. also if anyone has any plans for it, let me know. cheers boys.
