For those of you who have been tinkering with the .300 Norma mag. Please be aware that there are two sets of dimentions out there. The originals from Jimmy Sloan, and the revised dimentions dictated by CIp (etc). The revised case has slightly more taper and is 1,02mm longer than the original. There are also throat dimention changes.

Before you build a .300 Norma, talk to Dave Kiff at Pacific T&G or Don Heath at norma ([email protected], or you may find yourself with a wild cat that factory ammo doesn't chamber in!
