Lapua 223 gold box versus blue box

[Alpheus]

Is there a difference? I know other cases, like 6BR, have seen thickness changes between the two, is this the case with the 223rem as well?
I started out with 200 pieces of gold box, and need a couple more. Will I have any trouble if the new stuff is blue box?

What is the part number of the gold box?

No idea, tossed the box a while ago.

Some early "Lapua" brass was subcontracted and is heavier milspec. Later brass and for some time Lapua has made their own .223 Rem brass.
Not sure if this helps.

Mine is averaging around 94.5gr I'll ask a guy whose selling some to weigh his to check if there is a big difference.
