Hi kuduae,

I have the original Mauser listing, from Jon Speed book on Original Sporting Mauser Rifles, of all the magazine dimentions for each cartridge or group of cartridges.
By the way, not a Mauser, but my ZKK 600 original 9,3x62(1967) I post in the Rifles forum, has the following magazine dimentions:
Lenght: 88,5 mm
Rear width: 22,5 mm
Front width: 19 mm (if the width measurement is taken at the 85 mm lenght in the magazine, it is 20 mm...!)
And it can be loaded with 5 cartridges. Wich are feeded and ejected perfectly.
With 220 grs. FOX monometal bullets (made in Eslovenia), the maximum cartridge lenght with the bullets touching the lands is 88,5 mm. So I load it at 87,5 mm. Great!

Regards

PH
