That this forums title:
Beyond 5.56/2.23
Should be
Beyond 5.56/.223
Is it obvious that I am having trouble sleeping?
I hope that was not the reason for your having trouble sleeping.
Weird. I think the solution now is to make this 2.23 caliber and chamber an AR in it.

It would be nice to have it fixed though, especially with the reputation that this site carries.
Metric or American? This could pose an issue, either we can shoot a .10 cal or a mortar round out of our AR with this designation. 
I just assumed it was v2.23 of the “Beyond 5.56” section … :rolleyes:
Fixed now.
A 2.23 caliber would work out to be 56.642mm! Found a old U.S. tear gas gun here in Iraq marked 1 1/2cal which works out to be a 37mm. You could mount it under the barrel like a M203 and then develope the new loads.

Amusing, you are right. If I read that quickly I hardly notice.
