Icon a simple question about the bolter!

Ok. So I am sitting earlier today on my lunch break looking at the SM codex, casually ignoring the mock jibs thrown my way for playing this game, when it dawns on me...

WHAT THE HECK IS WRONG WITH THE BOLTER??

Now, what i mean is, take a look at the bolter. now look at it some more. now take a good HARD look at it. Notice anything off? ill offer a hint, Its the ejection port.
Now, i know the stats behind the bolter; it fires a .75 caliber, miniature rocket propelled, fin stabilized explosive warhead round out to a range of (roughly) 450 meters accurately {gw never really specified the max range or anything like that}. It can come in different ammo patters, the dragonfire, the kraken round, the hellfire, etc, which is awesome. i love reading about that lil tidbits of fluff. but i really want to know, how does the gun work.
You look at it, and the first thing i see is how the ejection port is nearly at the top of the gun, and not in-line with the barrel. And then i look at the pictures of the gun in action, and i see these really small shell casings coming out and i compare it to the barrel of the gun; total mismatch of sizes.

So, has anyone, at any time, read in a previous WD or BL book that makes mention of how this great weapon works?

Bolters use the same science as spaceships that travel through hell and allow teenagers to be transformed into nine-foot tall genetic supermen with direct neural interfaces to their unobtanium powered armour, to fight extragalactic bioengineered killing machines and sapce fungus bovver boys.

Don't think about it too hard, basically. It's a submachine gun that fires caseless explosive minimissiles, because at the outset 40k was hilariously, ridiculously over-the-top.

Except that it does have cases. We had a thread about this a while back and basically it amounted to "it's a caseless explosive sometimes."

It's not anymore?

The bolter is also supposed to fire caseless rounds, but in the pictures you always see bolters ejecting casings like it's going out of style. Also, they're supposedly deuterium-filled. Deuterium is a radioactively stable isotope of hydrogen, and according to my sources that's both physically impossible and a terrible idea for an explosive payload.

But, hey, chainswords!!!

It uses a depleted uranium core, not deuterium filled. I couldn't find any type of bolt filled with deuterium in it.

I'm no nuclear physicists, but deuterium can be used in fusion reactions with tritium or itself.

You've obviously not seen the 3rd Edition BRB then where it states that Bolts use depleted Deuterium.

Deuterium, in larger quantities, yes... like a compressed cylinder, roughly twice the size of a camping propane canister, with a microwave-emitting detonation device and a rip-cord primer handle. This, we call the meltabomb.

Or, on a weaker scale, in massive magneto-resonance chambers housed inside bulky gun-casings, deuterium can be superheated by electricity, then sprayed forward by the magnetic field, producing the effect of a bolt of bluish white plasma gas, racing towards an ork.

Or an even bigger scale, Kawasaki Ninja sized body of ceramic unobtanium-lined inter-stellar torpedo able to survive entry through an atmosphere, containing roughly a one ton TNT equivalent hydrogen bomb without the radiation.. This, we call a melta torpedo.

Back on the subject of Deuterium as a core, in the 3rd ed BGB (the paperback thing they stopped selling maybe 8 years ago?) showed a model of the bolter round, I think, or perhaps it was that edition's space marine codex. Either way, in the old design, it was recorded as deuterium, but I'm sure GW changed the name to depleted uranium when they realized that it was widely known that deuterium was just hydrogen with an extra neutron.

As to the caseless issue. I have seen a lot of diagrams showing bolter shells and their casings. In some, the casing is very short, just enough tubing around the bolter shell to hold it there until the primer is triggered, but in other cases, the casing is much longer, housing about half the rocket fuel inside the casing. I would presume this has to do with ammo stability and making sure the backing (and used primer) are ejected properly without any jamming issues. With an actual casing, you have something big to fish out when it jams, if you have a small back plate with the spent primer, you have little to reach for, and probably won't be able to dislodge it.

After some research, I stand corrected.

I'm looking for some where where the bolter uses depleted uranium and other than lexicanum I can't find one...so until proven otherwise GW hasn't retconned the Depleted Deuterium core of a bolt shell. (plus it was 6 years ago since 3rd Edition not 8)

That is the best, well thought out answer I have ever read! For whatever reason, I laughed my ass off! Have a couple rep for makin me laugh!
