Talk:M634 Experimental High-Powered Semi-Armor-Piercing

Note on Ammunition Cartrage Designations:

The second number in a cartrage designation does not necessarily indicate it's length. For some rounds it is the bullet wieght, or powder charge as in the 45-70 a US service cartrage from the late 19th century and for some like the 30-'06 it stands for the year of its military adoption 1906 and some cartrages have no second number like the 308 Winchester (7.62 Nato) or the 45ACP. It can also be just a naming nod to the origins of the round like the 7mm-08 Remington that was originally a wildcat cartrage made from 308 Winchester brass. Also there are lots of rifle cartrages that exceed 9mm even the above mentioned 45-70. Dagger133 01:24, 3 April 2007 (UTC)

I have managed to find a direct reference to the ammunition used in the BR55 in 'The Art of Halo 3'. It lists the cartridge as 9.5mm x 40 KURZ, leading to the conclusion that the final number is the case length after all, as the current day KURZ ammo has a similar ratio of bullet diameter to casing length. I can also scan in the image (which has all of the ammunition on scale next to each other) and measure off that if need be.

Analysing damage based on real life muzzle energies? I think not...

Most of this article seems to be devoted to comparing the muzzle energies of real life weaponry and ammunition to the damages to characters in Halo. For one, no accurate comparison can be made as the weapon damages in the game are purely for gameplay balance. The already inaccurate comparisons are made worse that there is no accounting made for headshot modifiers, etc. etc. I do not have time to change this now but will do so later. Anyone who is willing to do it before then is welcome. Diaboy 17:09, 21 August 2008 (UTC)

Wrong

When a cartridge is designated metrically, such as 5.56 x (45)<---- this number DOES designate length, just like the battle rifle's ammo type.
