I got that from Wikpedia. I scanned the article and couldn’t fine the caliber. I am guessing the article is correct and Wikipedia is outdated.
Actually i think it might depend on what army and or country you are in. lol

I thought that was odd too...didn’t directly mention the caliber in the written article. I did find it in the chart the author posted for comparison sake. It looks like it’s 7.62x51.
