I dont know any company outside of russia selling the 2,75" Tula shotgun brass. We see it here in germany allways as collectors stuff. I have talk with the russians on the IWA in Nürnberg( second biggest show after the shot show in america) when they hade sample of this brass on the stand.
There is a guy , Geno, on the double gun forum from russia, try to contact him if he can made this deal for you and send a box.
