    I have some once fired RP brass out of my 300 rum.
    Can I expand the neck on this brass for my 338 edge?
    Do to the availability I dont want to screw it up for either rifle.
    thanks

    yes, you can use a 338 ultra die backed out with a .338 tapered expander to size your 300 RUM to 338EDGE
