FYI: .223 bullets are specified at .224" in diameter. The measure .224" +/- a few ten-thousants (at least on my Starrett micrometer).

"just goes to show I don’t know much about that, what shoots a .223"

I changed the subject so we can spare those readers who actually wonder what size that nut is.   They won't be interest in who fired what and what size round was used.   I suppose I could regale you all with tales of firing the Vickers, Bren, and Sten on the ranges as a teenager.  All were 303 and all designed long before UK went metric.

https://en.wikipedia.org/wiki/.223_Remington has an answer to the quoted question.

But back to wrenches - My tool box still contains Whitworth, BA, imperial, and metric spanners.  Still have the BA taps too and some cycle thread stuff.   Who could possibly manage with only two sets of wrenches/spanners?  Yes, I used to own and maintain a couple of BSA 650s back when real bikes had a kick starter and sparks came from a magneto.
