Gold Box "Match"
All the Lapua .223 brass I have is in Gold boxes, is labeled "Match", and is high quality. I have heard of some Lapua .222 brass that was actually contracted from another manufacturer and was not up to the usual Lapua standard.
I seated a 55 grain Speer HP in a new Lapua .223 case. The neck mics about .2505, so it is a bit thicker than Rem. or Win. I would go with a .254 neck. My rifle was a .252 neck and I turned the necks on my Lapua cases.
