338 Win Mag

[Whitehorn]

Is a 338 Win Mag a necked up version of the 300 Win Mag?

Thanks.

The 338 Win. Mag is one of a series of cases based on the 458 Win. Mag case. Basically, the 300 Win. Mag is the 338 necked down and the shoulder moved forward 0.156", and the case lengthened by 0.120".

Necked up version of a 264 mag or necked down version of a 338 win mag.
