Hey... Finally, someone else in the gunblog world is as anal as I am

And I mean that in a GOOD way.

Lucky Gunner has decided to actually directly blog, rather than just dipping their toes in other folks blogs and comments etc...

And they picked a hell of an issue to start with: the difference between 5.56 and .223

Most folks just write that one off to "eh, they're mostly the same, but you probably don't want to fire 5.56 in a .223 chamber, just in case" and leave it at that.

I've explained the issue in greater detail, about pressures, lede etc... but then you go down the rabbit hole of what lede is, and throat geometry, and why that's important; and about the differences between pressure, and impulse, and time spiking, and pressure spiking, and obturation, and timing cycles of gas guns and...

It gets complicated. It needs thousands of words and testing data, and charts and graphs and....

Oh wait, somebody did that other than me... YAY!

Seriously, it's a great piece, and I hope they write many more just as good.
