Norma 300 win mag brass question

[MARINE308]

Question about Norma 300 win mag brass.I ran it through full length size and the case head is still sticking out of my hornady case gauge .010

I am using Reeding dies.Do I need a small base die.I bought the brass used

Have you tried chambering a piece of sized brass ?

Have you tried chambering a piece of sized brass ?

yes it chambers fine

 

[WeiserBucks]

If it chambers fine I'd run it as is . After a few firings you may need a collet die to sufficiently size the case , but my experience with Norma 300 WM brass is that the primer pockets loosen up before I need a collet die .

308, didn't see if the brass was new or used? Was the brass trimmed to spec?

 

[MARINE308]

Brass has 3 firings and it is trimmed to spec

You'll need some Imperial Die Wax if you don't already have some.
