I can not for the love of my life understand why the decision was made to make both a .50 cal ammo type and a 12.7 mm ammo type when its the exact same ammunition. Or is one of them a handgun cartrige, like the http://en.wikipedia.org/wiki/.50_Action_Express? And in that case, is the 12.7 mm in-game ammo the handgun type and .50 cal the rifle type, and if that is the case shouldnt the names be reversed, since the real-world 12.7x99 is a NATO standard rifle cartridge with the name 12.7x99 NATO (american designation .50 BMG) whilst the aformentioned .50 Action Express is the name of an american handgun cartridge with no international designation?

I've never seen the .50 BMG be called the 12.7x99 NATO before. Yes the 12.7mm in game is a pistol round as it goes in the 12.7mm pistol and the survivors rifle and the anti material rifle is obviously .50 rifle round.

Different case length I guess. I believe that .50BMG is the one produced in USA (12,7x99 used in Barrett M82, Browning Machine Gun...) while 12,7mm is the Soviet variant 12,7x108 used in various anti-material and anti-aircraft weapons.

The 50 cal MG / BMG is the 12.7 x 99mm NATO, even though it is also used before NATO was created and is used by other countries today. - Rifle/Machine Gun

The 12.7mm round is most likely the 12.7 x 33mm (.50 Action Express). The desert eagle was the first to use it. - Pistol

Common sense couldn't figure this one out for you?

Do yourself a favor and google a .50 BMG round.

Now ask yourself if that would fit into a handgun.

I all forgot that 12,7mm was used in pistols in this game. Never ever used the ammo type myself

It does. :laugh:

Their are several examples of pistols that fire the 50 bmg, but its clear in game that the 12.7mm and the 50 bmg are different rounds.

50 BMG is a rifle round.
12.7 mm is a handgun round.

12.7 mm has shorter case length & lighter bullet (that's shorter too).

I suppose they called it 12.7 mm because at the time all handgun ammo for semi autos was designated in mm.

But with dead money bringing the .45 into the game, that kinda went out the window.

Really though why not just use the .50AE?

Whilst we are on the subject of real world stuff not in the game: where is my AK???? Surely that would have survived a nuclear apocalypse.

12.7 mm is a slightly different bullet it is mainly the shape and wait. the 50 caliber round is desighned for a more powerful hit on the target and the 12.7 mm round is a smaller round with less stopping power which is why it has less damage in the game. i shoot guns quite a bit.

There is an ak-112 in FO 1 and 2. I think there is a possibility of it showing up in Fallout 4. The closest so far was the Chinese assault rifle, but that resembles the http://en.wikipedia.org/wiki/Type_81_assault_rifle#Variants (type 81). And in game it resembles the Ak-74u carbine, for the short time I have been on the forums, it doesn't seem too many people know that.

Based on what?

Nothing. But then again, there a possibility of my dead grandma showing up in FO4. A pretty small one, albeit, but you never know, do you?

As for the OP, as the others have stated:

Josh named all auto-pistol/smg rounds in mm and all revolver/lever-action rounds in inches to avoic confusion. It clearly did not work. :whistling:

And, as also stated, the .50BMG is quite a bit different than the .50AE. http://herohog.com/images/guns/ammo/all_ammo_comparison.jpg The .50BMG is on the top row, 6th from the right, just before the frickin cannon rounds. The .50AE is on the bottom row, 13th from the right, sandwiched between the .44mag and the .44automag.

The folks that have said that there's a tiny bit of difference between the two rounds are understating it a bit. And I should know, because I saw a gun once. :wink_smile:

-Gunny out.
