    My bit of advice would be:
    Don’t buy Hornady brass.

    Necks might split. What will be your process to expand up? Do you have mandrels to run it through an intermediate step?

    You can as people have bought .243 to size up to .260 but sometimes you get thinner necks. Buy 50 and try it. And nothing wrong with Hornady brass. Been using it in my match Creedmoors since 2008 and loads very accurate ammo.

    I hate Hornady brass so been resizing 7-08 Lapua brass to 6 creedmoor with zero issues so I would think you would have zero problems doing what your wanting to do!

    Hmm, 22-250 may work better, bit I could see how it could be more $$.

    Mac,
    22-250 does work but it’s short and there’s a potential for a carbon ring but I have done it. I trim my 7-08 to 1.940 then I turned .125 off a .260 Remington die and run the 708 brass through my 6 creedmoor then shoot it works fine and I have a lot if it. I plan on buying some good 6 creedmoor brass just hadn’t and needed some right now.

    I ran mine through my 6.5 CM Hornady die. Never split a case. Poor people got poor ways.

    Necking up 6mm brass should be fine. But how much are you really saving after 3-4 loads in each case?

    Hornady brass works fine if you stay with lower nodes. Some top PRS shooters are using factory Hornady 6mm creedmoor ammo, if the brass was junk they wouldn’t take it even if it was free.

    My own weighing of Hornady 6.5 brass has shown it to be pretty good actually in terms of consistency. It’s just soft. So stick with 2600FPS -range speeds 140gr, 24”bbl) for your first fire forming.

    Run the Hornady brass at hot loads and it’s one-and-done on the primer pockets.

    Hasn't been my experience. I have run my 140s at over 2800fps in a 28" barrel and gotten on average about 6-8 loadings on Hornady 6.5 brass before some pockets start to open.

    Hornady brass is good but expect to have to trim it if you load hot. It's a little softer than Lapua.

    Lube neck well inside and out. Then use a .257 mandrel in the expander die. Lastly use a .264 mandrel to finalize the process.
    Once you are at the 6.5 neck check the thickness of the necks to make sure you haven't made them overly thick. Most 6.5 Creedmoor reamers I've been around have a little extra neck clearance so the variance likely won't cause anything but more neck tension.
    DISCLAIMER: just my opinion as I am rich enough to own both 6 and 6.5 Creedmoor brass. :cool:

    I must have an extremely fast Barrel shilen select match 28 inch, has no problem with Hornady brass muzzle velocity 3150 super accuracy with 44 grains of h4350 130 grain Berger hybrids Tactical.. I also get eight loads out of my brass before primer Pockets get scary

    Brownells has Peterson brass for $43 a box large or small pocket. It comes with a nice plastic case and is leaps and bounds better than Hornady brass. Buy once cry once. You will be better off in the long run and save a lot of time and hassle. Heck, they even have Starline for $49/100 bag. It doesn't get much cheaper than that and again way better brass than Hornady.
