Lee Precision 223 Remington Ultimate Rifle Die Set (4 Die) vs 223 Breech Lock 3-Die Set

I am trying to determine if the Lee Collect Die for neck sizing only (included in Lee Precision 223 Remington Ultimate Rifle Die Set) is of much value for reloading purposes for magazine fed semiautomatic rifles.

As I understand it the Lee Collect Die for neck sizing only is best for once fired brass in bolt guns not recommended for semiauto.

Is their a method or process that the Lee Collect Die for neck sizing only could be of benefit for magazine fed semiauto rifles?

I am just trying to an informed decision and determine if the bundled savings in various kits are worth not having the Collet Die. They include the .223 Breech Lock 3 Die Set which does not have the Collet Die. To Purchase separately later would negate any saving.
