I´ll try and make exact measurements of the Buffalo Werder cases (to make it a bit more complicated, they´ve got the Mauser dished base). I´ve got the Hensel mould ... but shot the Werder again yesterday. I´d re-set the front sight and got ALL the rounds centred. But couldn´t get the height anything like standard (shooting from a very stable rest). They were either much too high or too low and much too varied to have been me. So I can only assume that it´s the weight of the bullets. If the carbine can shoot an accurate, centred group and only the height varies, it can be little else, and all I can do is to work on the ammunition. (With all your help) I´ll work on getting a sizing die.

BTW, Patrick, I was astounded at the eGun auction result. Sometimes quite rare items go for practically nothing and then ... goes through the proverbial roof.
