I was just reading a bit on this cartridge. Based on the 416 rigby case but shorter than the 338 lapua. Sounds like an amazing round, with an oal designed to fit in Rem 700 long actions. Just wondering how difficult a build this would be with the Rigby's huge case head.

Go and have a look on Snipers Hide.com - the beyond 1000yrd topic. The .338 Norma mag discussion is up to 9 pages giving details of rifle availability, dies, loads etc.

And yes, when loaded with a 300grn Sierra MK bullet it fits into a Rem 700 or AI magazine.

A very good long range target round. As a hunting round I prefer the .338 Blaser
