I have been doing some reading on different forums and there seems to be a difference of opinion regarding the need to resize new, unprimed cases. One opinion was that new cases already come resized and recommended chamfering only. The other article recommended running all new brass through the resizing die. What do you guys do?
 
I just load them and they work fine. I've done this with many different calibers. I don't bother to champher either. Lots of things that are good practice when loading hi-power, bottle necked rifle brass are not necessary when loading straight walled pistol brass.
 
I've bought a 100 rnd bag of Winchester new unprimed cases and with that I sized it then I measured the cases and had readings of 1.158 to 1.150 ( some case openings were not square ) so then I trimmed it all to 1.150"
 
just got done processing 50 new pieces of WW 303 brass...

size and trim to uniform minimum oal and chamfer the flash-hole...if you look inside a new piece of brass you will see some swarf from the extruding process (I am guessing thats where it comes from...) its like a lip on the flash hole...to make my brass all the same, I always hit the flash hole once.

its a PITA but it should be done IMO.

there is some brass that I didn't need to do...of course, this was Norma brass for my 7.5x55. I have also heard Lapua didn't require processing NIB...but I wouldn't believe it until I saw it on my own calipers.

The last time I bought new brass in 44 mag(winchester) I measured them both before and after resizing. There was three thousands difference in diameter. This will make a substantial difference in bullet pull. With inadequate neck tension you will end up with erratic velocities.

Sizing new cases does three things:

1. Verifies that the case is the correct diameter.

2. Irons out any dings in the case mouth that occurred during shipping and handling.

3. Verifies that there is a flash hole.

Then check them for proper length.

You should also lightly chamfer the case mouths after resizing and checking length to remove any slight burrs left from the manufacturing process.
 
Ditto with what Bushmaster and everyone has said.

I resize new brass to keep the variables down, because I feel whatever results I get are more repeatable on subsequent reloadings where I am, of course, resizing.
 
Same here!

Take a close look at the mouth of ANY new brass. It's dinged, dented, and not square. Try putting a chamfer on something that's not round! The chamfer will NOT be even. Parts of the mouth will be chamfered, other parts won't. Brass is dumped from one container to the next during manufacture, it gets beat up pretty bad.

There's a third player in the premium brass race now. Nosler is offering match brass in a few popular rifle calibers.http://www.nosler.com/index.php?p=9&bullet=13

At .50 apiece for .223 to over a buck for .280 ackley improved, it's expensive! IMHO it's BETTER than lapua or norma because it's prepped and ready to load.
 
I just bought a hundred pieces of .35 Whelen brass. They are dinged up pretty bad from handling. I plan to resize each of them, if for no other reason than for uniformity's sake.
 
+1 with resize ALL cases when reloading, even new commercial brass, for all the reasons given above.

Good shooting and be safe.

You don't need to resize them just do the initial sizing with your carbide sizer die and you will be fine. Chief ;)
