.303 cartridges usually have a bullet diameter of 7.9mm+.
The .303 British does. This would be diametrically smaller than a garden-variety 7.62mm bullet. So it would be very odd to call it a .303 as it is unless you use a different system.
That and I have a 7.7x57 of my own, to create confusion...

.308 is a larger number than .303 btw

They generally aren't measured by actual calibre. That's not how the system works.

sorry for giving honest critique of the oligarchy
m@ - March 2, 2011 04:34 PM (GMT)
omg ekraysia = spizania?
it doesnt matter what the fucking notation is because this is NS/SMS and we can call our rounds wutever we like
Ekraysia - March 2, 2011 04:35 PM (GMT)
if it doesnt matter what the fucking notation is then call it 12 guage which is infinitely better
m@ - March 2, 2011 04:36 PM (GMT)
sry there is a difference between wild inaccuracy and 'doesnt follow IRL notation conventions'
Praetonia - March 2, 2011 04:41 PM (GMT)
Some RL rounds are the stated diameter. Others aren't by a little, but not the same amount each time. So any approximately correct diameter is valid. This is different to 12 gauge which is a clearly defined convention.

Critiquing the nomenclature is not really an honest critique.
Its not a problem with the design, it a personal problem you have with the designation...get over it.
but to keep you happy,
M@, I hence forth revoke your membership in the C.I.P. you may no longer use or claim to adhere to the standards and practices of the C.I.P. , in short do whatever you like but dont expect any further support from the C.I.P. ... additionally I will be notifying SAAMI - youre fucked now son.

I don't know why they call it .308, but the .303 round is actually bigger than the 7.62 NATO (".308" to the "I bought my gun at Wal Mart crowd"). I personally take great pleasure in asking for 7.62 NATO at gun stores.
.303 is 7.7mm, so it's actually bigger. Everybody knows the .303 Mk.7 round is mor destructive than 7.62 NATO. I think. Lol.
