    What kind of loaded neck diameters are you guys getting with nosler brass or the new batches of federal brass? Im using an old batch of federal from way back and im about to send my forster die to have the neck honed out and id like to know how the nosler or new federal are running for when i need new brass.

    I just happen to have 10 loaded rounds left so I measured them for you. The brass is 2010 Nosler 300 RUM. The loaded neck diameter is .339"
    These cases were not neck turned and are on their first loading.
    Hope this helps.
