    Never expanded or necked down brass before. Pretty much just been loading “standard brass” til now. I need to neck up some 6.5 to 7mm. Does anyone make an expander for that or do I just go to a 7mm and expand?

    Any advise is appreciated.

    That is a small increase I would just do strait 7mm expanse with the die youre after.
    When fire formed check all specs.
    but always look at all specifications before fire forming also

    You can do that with the die you use if it has an expander in it.

    I'm refering to your case length mostly and head space (where is ???)but all is advisable

    Just make sure it's a tapered expander in the die and don't force it. Used a Redding 338-06 die to neck up and the expander wasn't tapered, destroyed a piece of brass by forcing it.

    I would lube the inside of the case neck. I use a nylon brush and spray some case lube on it then run the brush in the neck before expanding.

    Yes. I have a K&M expanders with a good taper to it. I did expand one as a trial and it went well was just cornered about donuts from the process.

    Tapered, yes..
    Great for forming, no....

    Best way theoretically, would be lube inside of neck, expand to slightly over size your going for, then neck down, leaving slight false shoulder. I would probably recomend anealing at that point.

    That's the correct way to do it anyways.
    Me i'd just lube inside of neck, and run it in my full length sizer. :rolleyes:
