Tx, what goes into resizing the 22-250 brass to Creedmoor?

What is the advantage of the Creedmoor or BR over the 243?

Since my Creedmoor sizing die is a bushing die,I resize the necks with my 260 Remington neck sizing die and then run them in the Creedmoor die. I check the neck thickness,and if needed I turn the necks.

25cshaefer,I use 243 brass for all of my 260 Remington brass,but 22-250 works better for the Creedmoor since the Creedmoor is a lot smaller length in the body of the shell than a 308 family cartridge.
