Re: new deformed necks
I'll partially resize them, if using a FL sizer leave a 1/16th-3/32" or so gap between it and the shellholder.

Re: new deformed necks
I run the brass up into the sizing die over the expander ball (not high enough to size the case). Then chamfer and debur, then it's ready to load. You will scratch up the bullets bad and you will get different neck tensions if you just load them out of the bag.

Well, it depends...
I bought two bags off of here back in March '08 and didn't open them for a good year, when I saw a few dinged up ones through the bags.
I opened both and have about 13 that are so freakin' messed up, I can't even figure out how they got that way. It's not like they were crushed, because the mouths are not smashed in. Some mouths are, but they're not creased. It's truly a Kodak moment.
I can't fix those, but I was able to run the minorly mucked up ones through the die and they came out fine.
I need to send them back to Winchester with a sob note asking them if they have any guys on the production line bagging up the rejects.
Maybe they'll send me a free bag or two?

Ditto what Chad said.
A lot of the case mouth damage is from tossing the bags around after leaving the factory.

Re: new deformed necks
A good way to do it is get a neck expander die with the correct mandrel and insert it into all the necks .
Then give the internal neck a good polish.
This can be done with an old bore brush wraped in some fine steel wool and rotated in an electric screw driver .
Polish up the external neck by hand with steel wool.
Then chamfer the case mouth .
Then size the case neck for the bullet.
This will result in more even neck tension and bullet pull ( push ).

Re: new deformed necks
I don't sweat new brass: I just stick the pointy end of a loaded round into the dented case neck and opent it up enough to seat the bullet.....

A tapered starter punch works very well, also. Heck, I've even used a small set of needle-nose pliers for this task!

Re: new deformed necks
I run them through the 650, using only two stations. First station I use a Sinclare expanding die to get rid of the deform necks, second station I use a neck sizing die to uniform the neck tension. Do not like using expander balls being pull through the neck, because I find it makes the headspace not uniform, necks aren't concentric and fatigue's the necks. Then I trim/chamber the brass to a uniform length. Any other ding in the brass body will blow out after the first firing.

Re: new deformed necks
I use a punch that roundifies the neck before sizing the brass. 308s fit up near where the punch rolls out towards the grip, 233s use the punch near the bottom. Just stick it in there by hand and give it a little force--then run it into the die for actual sizing.
