Have a bunch of loaded cartridges which were neck sized for a different chamber.
Is it ok to pull them and fl resize without the expander ball?
 
As long as you can keep the lube from inside the case I see no reason why you can't but I'd take the decapping pin out and leave the expander on.
 
No! The resizing will squeeze the neck down and the bullet with it. The neck will expand a bit but the bullet won't. You will wind up with a bunch of undersized loose bullets.

Bottleneck FL sizing dies press the neck in and then the expanding ball opens them back up to the proper size on the way out.

I bet highlander missed the "loaded" part. Unless when you say "pull them" you mean pull the bullets, dump the powder and start over with primed brass. In that case he's spot on. Leave the expander but remove the decapping pin if you can. Don't just raise the decapping rod because you'll get a lot of interference if the expander is up in the neck portion of the die. Personally, I'd just decap and size as usual. Save the primers for target or plinking rounds.
 
With standard dies, NO. With bushing dies YES. When using standard dies without an expander, a boatail bullet could be used as an expander when seating if you chamfer the case mouth enough.The seating stem may leave a ring/mark on the bullet nose. Not a good method. This is using a jacketed bullet. Lead bullets will not work.

Afy,

Get yourself a Redding Body Die. There is no decapper or expander ball with this die, and it only resizes the case body (not the neck), which is what you want to do. Using this die, you will not even need to pull down the cartridges. Simply lube the outside of the case, size them (screw the die down until they fit your chamber), and then wipe them off. It's a handy die to have.

Knowing more information might save some hastle..

If you know the load data, (loaded them yourself), and it's not even near the warm side of things, or where you'd start if you were working a load up, If they're loaded to spec dimmensions, If they'll chamber in the gun you want to shoot them in, you might just do that.

Would I do this with the loads that I've got the bullets seated out just shy of the lands in my Ott-6, and shoot them in my nephews gun of different manufacture? No.

But, I have swaped rounds that were 'neck sized only' loaded to spec lengths between 30-06 rifles. Done the same with .243 rifles/ammo with no affect at all.

There are enough differences in retail ammo case thicknesses that affect more. Will these neck sized rounds be as accurate when fired from a different chamber/barrel than what they were worked-up/fire formed in? Hard to say, but to me it's not worth the hastle of resizing the cartridge as long as it will chamber safely in the rifle you intend to shoot.

If they are suspect 'warm loads' or you didn't create them yourself, then pull the bullets. Dump the powder, and resize/reload, starting from scratch.

I have the Redding Bushing Die (competition), I have the three piece one.. seating, neck and body. I also have normal three die set Type S.

The loads are fairly hot... and do need to reduce the charge per what QL tells me, also will need to reduce COAL from 2.915 to .2860
