The .338 WM is actually shorter than the .300 WM.



The .338 WM specs are as follows:



The .300 WM specs are as follows:



These images and specs came straight from the Nosler 7 reloading manual.

Re: High Quality 338 Win Mag Brass-Need Help!

Win 338 brass is decent stuff.
I've made 338's from 7 rem brass and it can be done but win 7rem brass will have very thin necks. Rem 7rem brass is better for necking up. You will need to go to 30 cal first unless you have a tapered expander.
I've pushed 300 win shoulders back for both 7rem and 338 win brass and they wrinkled a bit but shot fine. Not quite as bad as fireforming 7rems into 7stw's I suppose... Don't try that one at home boys and girls.

nope, had both a 7 rem and 7stw on the bench at the same time and chucked the wrong one in and pulled the trigger. The 7rem will headspace off the belt when fired in a 7stw but will blow the shoulder out and leave you virtually no neck. Not much different than fireforming "improved" rounds other than 7rem brass is to short.
