I pretty much always anneal after moving metal that far, not doing so will leave a lot of stress in the brass and greatly elevate the probability of neck cracking.
Presume you are looking to get a better fit of the neck in your rifle's chamber, but, as you are probably aware, you must ensure there is enough clearance for the brass to release the bullet upon firing as your new neck will be made from the thicker brass from the body of the .223.
Actually my goal is free available brass ,don't mind the work involved. The new brass chambers fine I guess I should make up a dummy round and see if it still does. Can't tell with my eyes but I suspect IVI range brass has a crimp in the primer pocket?
IVI brass does have a crimp, for military use.
Even if your brass chambers a dummy cartridge, you still need to ensure there is enough clearance to release the bullet upon firing.
If it works, you will also get the benefit of having closer fitting brass, which should help accuracy.
Try a starting load, fire it off, then see if a bullet drops down inside the fired, un-sized case.
If it does, you're good to go. If not, you'll have to either inside ream, outside turn, or switch brands of brass.

Remember; starting loads ONLY!!!
Fired an altered .223 Winchester,Federal and IVI with 24gr of win 748/50gr SP No issues or pressure signs?/primers normal. Bullet freely enters entire neck with fired Winchester and Federal brass .IVI bullet enters 2/3 of the way before binding. Will these require neck reaming?
Yep; this makes sense as the IVI [military] brass is much thicker.
Yup now that I have a AMP machine i anneal all my brass

This is off topic, but a box of lapua 222 rem brass is definitely expensive, but not hard to find. Those cases will last you for a long long long time. 222rem brass lasts forever if you keep low lower pressure rounds, anneal and set your dies up right so as to not overwork it. I shoot almost every week and I've got 222 brass that's over 5 years old. I shoot them until the primer pockets start to "feel" loose.
As for your original question - yes, I would think annealing after working the brass that much is a good idea. I would also recommend uniforming the necks after your first firing.
Love the 222 - have fun!
Measure first. You may, you may not. - dan
There is an anvil tool that will let you tighten those primer pockets up too, though I can't recall who makes/made it at the moment. - dan
