Mike,
Interesting, do you have the measurements for your friends cartridge?
I believe they are most likely similar. The 358 Norma Mag, 358 STA, 358 Entekin and the 35 Zimmerman probably have more similarity then differences. I never knew Mr Zimmerman (I believe his first name was Bob), who was a tool and die maker, did make his own chamber and sizing die reamers for this gun. It is my understanding that Mr Z wanted what he called the ultimate long range Elk gun. He made one rifle for himself and then the reamers were used for my rifle. I would imagine as Mr Z was designing his cartridge, one has to believe he was veting the available information on other designs and may have used some of Mr Enterkin's data if available. Did Mr Enterkin publish any articles or information concerning his cartridge design?
