I would like to know the actual diameter of the case, please. For example, FC measures .372" and Winchester .374".

Re: Lapua 223 Brass

This will vary if guys measure fired brass due to chambers.

I assume that you want the virgin diameter?

Yes, but if you measure the case immediately forward of the extractor groove, it will be close enough for me.

This is Virgin diameter right out of the box new!
Confirmed on my Mitutoyo's also, but taken with the digital for ease to read in the picture.
