So I think we should make a thread about and list all the calibers and corresponding bullet sizes/barrels that it goes along with.
Shattered Skies, I´m not exactly sure what to make of your post. I don´t want to act smart, but I see some misconceptions here.
First you say you want to make a reference of "bullet sizes" with their respective barrel calibers, but your own conversion of the metric to
imperial scale only names the bullet sizes. Or, as Orangetom said, the 5,56x45mm bullet doesn´t have a caliber of .223 (remington); instead both the
5,56mm and the .223 have a barrel caliber of .224 inches.
For a comprehensive list of bullet sizes in metric and imperial measures vs. their caliber there is a more or less
on Wikipedia, or see Orangetoms post.
Second, if your idea was to simply convert the metric measures to imperial measures... well, one just can´t do that. The basic problem is that every
bullet measure indication is not just that, a measurement. It is also an individual name for a very specific build of the bullet.
Again lets take the 5,56x45mm NATO and the .223 Rem cartridges. While these two are similar from their outer measures, there are also distinctive
differences between them that are not covered by the measures alone. For example firearms built for the metric cartridge are technically able to
handle higher pressures than those built for the .223 Rem; which means firing a 5,56mm from a "weaker" rifle optimized for the .223 can lead to
dangerous and even catastrophic results.
What this leads us to is that, if we want to be precise and on the safe side, we may never call a 5,56x45mm cartridge a .223 Rem in short, or we may
not call a 7,62x51mm a .308 Winchester, we even have to distinguish cartridges like the Mauser 8x57mm I from the Mauser 8x57mm IS
we are speaking of different cartridges here that SOMETIMES need entirely different weapons.
