Questions about Lapua brass

[Lucky Shooter]

I have some Lapua 222 brass with three different markings on the box and head stamps:

Gold box and head stamped with MATCH
Blue box and head stamped with MATCH
Blue box and headstamped without MATCH

Is there any significance in the MATCH designation ?

I haven't measured neck thickness for comparison.

Would appreciate any info on this.
