new brass requirements

[badnova]

I just purchased 1,000 new unprimed WW .308 brass for my RRA 308. My question is since this is new brass is resizing required before the first loading?
I've reloaded for years but never bought new unprimed brass before and I would rather avoid running 1,000 through lubing, sizing, washing, etc., if I don't need to.

I'd rather just prime, charge, seat bullet and crimp for the first time.
Thanks

You can probably get away without sizing, as the brass should be in spec, but many experienced reloaders, myself included, size new brass.

Blasting ammo. Just load it and shoot it. What is your goal for this ammo?

New brass often has dents and out of round mouths from shipping. I run all mine through a neck sizer, just to make sure the necks are round and ID is the same for all.
If you plan on crimping the loads you might want to check the OAL of the brass too. That is another spot new brass has varied a time or two in my experiance.

I treat it as once fired: size, trim, uniform pockets, deburr flash holes (on certain brands) and turn necks if it's to be used in specific chambers.

I do most of my brass prep before it ever gets shot.

Full length size
Trim if needed, which is rare.
Uniform flash holes
Uniform primer pockets
Anneal
etc...

This is what gets run through my bolt gun, if I had something like an AR I doubt I would get all that crazy with it. But I would still FL Size due to dings and dents from shipping.

+1 on the length sizing as all new brass I have purchased will differ in length. Mostly the necks are OK but if I get one that's obviously out of round I will neck size it. I use the Lee trimmer and the FCD will work 100%.

I always full length size new brass. I deburr if needed. Except for the cleaning, it is treated like once fired brass.

I do the same thing. In the long run it just makes the loading easier.

I've done both full-length and just neck-sizing and never had one that didn't fit. But if I had a rifle with a tight chamber, I might full-length size just to be sure.

The brass is usually plenty clean when new, but like others said, the case mouths are sometimes out of round and the case mouth rim is relatively rough and jagged. So I always at least neck size.
