@Micky Duck can you expand on this?

Wondering what you were talking about as I had always taken the box figures for granted e.g. 7mm/.284 I took a look at my wall conversion chart. And what do you know, 7mm is 0.2756". SO measuring a 7mm/.284 ELDX with the verniers comes in at 7.17mm/.2820 and a .270 NBT is exactly 7mm/0.2755. So now that my mind is blown, what is up with the naming? or measuring system seeing as they don't actually convert? Also, by the chart 5.56 is not 0.223" yet 7.62 matches 0.300".
