new .223 brass

i got some new .223 remington brass today and have a newbie question. With brand new brass, do you guys resize the brass before priming and loading? i've loaded some for this caliber, but it was all once fired brass, so of course i resized and such. i just haven't loaded any new brass for it yet and was just wonderin'........thanks in advance. cheers, hvychev77

There was a thread the other day about this topic. As far as my reloads I do resize, trim, chamfer, and deburr all new brass. This assures that it will all be in spec and will all be at least the same length as my fired brass after I process that. This will keep me from having to reset the length any dies that I crimp with and makes my job easier. FWIW I have found brass with out of round and crushed necks as well as .05 length variations. When I reload all my rounds are a standard length with shoulders at a certain spot for a particular firearm this simplifies a lot of the things that cause other reloaders problems.

This question has been discussed on this and other forums more than once.

The only new brass I resize is for a 460 S&W Magnum revolver and that's only because the bullets can't be seated firmly enough not to back out under recoil unless I do and that's in spite of a good crimp.

Before I would go to the trouble of re-sizing a gazillion brand-new cases, I'd load a few of them, and see if they cycle in my gun.

Take a close look at your cases.
If they look good, they probably are good.

If you go into monkey-plugged-into-an-iPod mode in front of a progressive press, you might end up with with a big pile of disappointment.

Pay attention.

I like to size new brass, trim it, as well as deburr & chamfer it.

Some folks just load it up and shoot it. :)

I bought new .223 brass just once. A hundred Winchester. As I recall, lengths varied from 1.748 to 1.762 or thereabout. Some necks were oblong or D-shaped rather than round. A few necks were cut at about an 85-degree angle to the case body. A few had burrs in the flash holes; one had no flash hole at all.

I FL sized them all and trimmed them all to 1.750 unless they were already below that. I chamfered and deburred them all and addressed the flash holes. The ones I've loaded and fired shot fine, but they were not ready to do so from the factory.
