Artillery Terms


Ok, I do know my small stuff pretty well, but today a shooting buddy asked me a question I couldn’t answer: In, for example, 16" 50 caliber or 5" 38 caliber, what does the “caliber” number mean? Is it somehow the case length?
I’m sure I could hunt the net, but I figured I come here for a reason.
Thanks in advance.



This describes the length of the gun barrel in relation to bore diameter i.e. 16" 50 caliber, the barrel length is 50 x 16" = 800 inches.



Or as said elsewhwere it is the “caliber length”. Brian would that be used in English as well?

Oh boy! Just had a cold shiver running down my back!
And here is what you get in the web! Saying women are clueless? No! But people not knowing anything should better remain silent! Here you can see compressed nonsense on almost any subject:




Well, hmmm sometimes silence in golden.



In Europe at least, the length of the gun (for example 70 calibers) is often noted this way: L/70

Be aware that there may be differences beyond barrel length. For example, Bofors 40 mm L/60 and L/70 are totally different guns firing very different ammunition.
