338 EDGE first test loads

[Topshot]

I am making up some 338 EDGE loads for the first time.

I started with new Remington RUM brass then uniformed the Primer pockets and flashholes. I then and run them through a K & M mandrel to expand them to .338 cal and then neck turned them to .366"

These cases look ready to load but do I need to now run them through a .338 EDGE FLS die?

These cases are only to run the barrel in so I would like get away without Full length sizing them?

If the brass will cycle in your rifle and will hold a bullet (tight enough), then you should be good to go.
