Thread: 338 ARC - An Early Guess At Reloading Data

Can you please tell me where you found the final dimensions of the 338 arc cartridge?
I looked up these ones: https://www.pacifictoolandgauge.com/..._p_119606.html
Which is a copy of their reamer print. And I also necked up a 6.5 grendel Case and fitted a 338 projectile into it.
The dimensions on the reamer print are quite close to my mockup round . But my mock-up round seems to have a way longer body than that of the hornady pictures.
