Campher the mouths a little, straighten up any dented necks and then you can load it up and fireform it to your chamber.
I then uniform the primer pockets and do the flash holes, but that's just me.

Bullet Pusher,
We recommend running it over an expander mandral to ensure that the case mouths are properly rounded out, just in case there's any denting from shipping. This, or a quick necksizing with an expander ball if you don't have the mandral. No need whatsoever to size, uniform primer pockets, trim or even chamfer. Can if you want, but it's not needed, and probably won't gain you anything in most rifles.

I have followed what Kevin said and found that it provides great neck tension uniformity. I bought the Sinclair body and 3 sizes of mandrels for different calibers...
+1, Until fire formed I can't find a reason to labor for diminishing returns. As mentioned I would clean up dented necks if present but I can't ever remember purchasing damaged new Lapua brass.
A couple/few years back, Lapua was having QC issues, from super hard necks, missing pieces, to dented in case mouths, even after switching to plastic boxes, so go figure?
I'm a Lapua fanboy, but it's still man made stuff and can stand some attention.

I would do a full re-size for every case. Just to straighten her out and make everything consistent.
Also, you will find for some guns, such as a Savage with really tight chambers. Full Resizing will be mandatory for about 30% of the cases, because they will fail to chamber.

This. My process is redding body die then lee collet neck sizer. I would be lying if I said I just didn't load them out of laziness from time to time however. When I measured headspace with the hornady headspace setup, I found that my body die bumped the shoulder back about .002 from the out of box guys. Both ways ran like raped apes through my 10FCP HS.
With lapua I usually just visually inspect them and deal with any obviously bent case mouths but that's about it. After the first firing I neck size, trim, etc.
I haven't seen much need to debur the flash holes on lapua ever. On Winchester/Remington brass I do a full resize, trim and flash hole cleanup on brand new brass because it usually needs it. After that though it works well so I'll use non-lapua if I'm not being lazy/cheap or can't find lapua.

I agree with Kevin. I got a box from Sinclair that got damaged in transit. The plastic box shattered, and about 11 necks were damaged. After I accidentally wrecked one in using the expander ball, I used needle nose pliers to gently take the worst out, and then expander balled the rest, and they are perfect. The other 89 were fine to load and go.
BTW, Sinclair gave me free shipping for the next order because of the one I couldn't save, even though I admitted to my part in the failure to save. Can't ask for better CS, can you?
