New Brass Question.

[jasons85gt]

My cousin pasted away this year and I was given all his reloading items and I found 2 new unopened boxes of Hornady 308 brass , Do you guys run it thou the dies before reloading it or should it be good to good for loading out of the box. I've never had brand new brass before always used. Thanks Again!

I size it still.

Some do, some don't, and some kinda do.
On the rare occasion I get new brass it seems the neck area needs some attention. I size to even out the necks without setting the shoulder back. It should already be set to minimum standards out of the box. Started checking to see if flash hole in primer pocket is open. Have always deburred new cases. Then make sure it chambers before loading a bunch of them.
Depends on your needs. I'm just an average plinker. Target and long range shooters will be much more particular.

I would . At least a partial resize with the die a smidge off the shell holder . It's well worth the 5 minutes it would take to run them through .

A case gauge would be really helpful just to be sure, but hornady is pretty good stuff- 6 one half a dozen the other.

Just be sure to "lube" the cases before you run them through the sizing die. Otherwise you're gonna have to search for my post on "stuck case removal".

This is generally not problematic with new cases (that have never been fired and have been superbly manufactured to spec) unless/until it becomes problematic...

I use "Imperial Sizing Die Wax" for match-grade reloads (a little dab along the neck and case body goes a long way). Hornady "One Shot" too for other bottle-neck cartridges. Many prefer other case lubes.

I'll check the necks for 'flat' (out of round) ones and bump them over the expander button. I also check the flash holes and will chamfer the inside of the neck. I do not run all the cases into the sizing die if they are new.

From Starline Brass' website, FAQ:
Does one need to full-length size brass prior to loading?

Generally speaking, Starline cases require no resizing prior to loading. Due to variances in diameter of different bullet types, it is a good practice to size the case only as far down as the bullet seating depth. When full length sizing is required, it will be noted in the box with the brass

[frankski]

If the brass is already sized correctly, running it through your sizing die will have little or no effect. No harm.

However, by sizing, you will catch any dings or errors that slipped through the manufacturing process. Neck tension will be consistent.

[Twoboxer]

New rifle brass is minimum- or under-sized out of the box. As frankski said, full length sizing new brass will have no effect (and cause no harm) if the necks and bodies are correctly shaped.

If any are not, the sizing corrects it.

You can elect to look at each case and try to judge whether it needs work, and/or you can take a chance and find out which ones have dinged necks from shipping when you try to reload them.
