However, this is extremely contradicted.

Both the fluff

Cyrene closed her eyes, waiting for the hammer-hard impact that would spell her destruction. Despite the moment, she felt a smile tickling her lips. This was an insane way to die. There’d be nothing left to bury.”


and the art

and the models

show barrels that I am pretty sure are beyond 1.0 caliber.

Do heavy bolters fire some kind of double-sabot rounds or something?

The first picture you posted shows the muzzle being much too large for anything that would be able to fit in the feed they have attached to it.

EDIT: and I just saw the casing that is falling from the weapon in the first picture. Look at the size of the casing, there is absolutely no way anything that casing was holding could have been fired out of that weapon. It's preposterous ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7695111.page http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7695111.page GMT Re:Heavy Bolter Shots ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7695138.page http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7695138.page GMT Heavy Bolter Shots

That is artist impression to make it look more epic.

the buller would be 26mm diamter and the base of the shell about 41mm


remember "50 cal" = .5 caliber

AR-15s for example:

You can see the exit hole for the projectile is much smaller than the opening of the muzzle brake.

This is for many reasons, but probably so that the thicker barrel will be able to absorb more heat before it warps. Which is probably helpful when you're dispensing high caliber rocket rounds at tremendous volume like a heavy bolter would be.

I mean, if we're talking a 19-25mm round (.75-1), the muzzle brake for it could easily be 4-5 inches across for a battle-hardened weapon like what you'd issue to a Space Marine. Remember what a Space Marine is and what he does. Hitting somebody/something with your heavy bolter probably isn't out of the realm of possibility, lol.

As far as the size, shape of the round, the bolt is a two-stage, self-propelled munition. We really have no idea what it would be shaped like. It could be long and slender like a 25mm canon round, or it could be short and stumpy like the old 20x22R. I mean, it doesn't need a ton of propellant in the case because it's only using it to exit the barrel.

Either way, if there are discrepancies in the art, it's because it's art, and artists are no more experts at warfare than Black Library authors. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7695459.page http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7695459.page GMT Heavy Bolter Shots

I agree with everything your saying and as I said I think it's mostly this.

But when you depict a heavy bolter with a muzzle break that is easily 8-12 inches in diameter then there is no possible way it is for anything but a tank cannon equivalent.

Rule of Cool really takes precedence when an artist is depicting war- and it's always been this way whether it be sci-fi novels, fan-fiction, movies, or any other medium. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7695795.page http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7695795.page GMT Re:Heavy Bolter Shots

Exactly. 1.0 caliber is one inch in diameter, meaning that obviously, the barrel opening is 1 inch in diameter.

I have a HB marine here with me and he looks like the lower model. I don't think he's drilled at all, the HB looks like that.

That's a .30 caliber machine gun. I don't know how big that tube is but it looks like you could stick your hand down it. That's obviously not the barrel, and is in fact an air duct.

Bolts are fired much like bullets and after leaving the barrel the rockets in the bolt fire and speeds up the bolt toward its target]]> http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7696493.page http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7696493.page GMT Heavy Bolter Shots
The big muzzle is so that the rocket propellant expanding doesn't warp the end of the barrel. If there was no big honkin muzzle brake on there you'd just feth up the barrel rifles!

A lot of it also has to do with making the model functional as a game piece, both identifiable and durable. Plastic IG heavy stubbers are huge compared to FW DKoK heavy stubbers, with barrels that look like they're easily 7 or 8 inches thick, but they make much more resilient game pieces. Something I've found quite often when playing with DKoK models, with their more realistically sized weapons, is that people often just can't tell what's what. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7696860.page http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7696860.page GMT Heavy Bolter Shots bolter shell in FFG's roleplaying games, not a heavy bolter shell - they're even bigger.

That is correct. Stated bolter caliber has been fairly consistent. Regular bolters are .75 and heavy bolters are 1.0]]> http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7699893.page http://www.dakkadakka.com/dakkaforum/posts/preList/641396/7699893.page GMT Heavy Bolter Shots

It's also possible the definition of an Inch changes in the next 38,000 years. An inch was something like 3 barely corns laid end to end. Maybe Chaos mutated the barely corn after Humans genetically engineered it in the dark age of humanity. Hence a 40k inch is actually 4 21st centry inches.

I was always under the impression that bolters, regular bolters, fired .75 calaber rounds, while heavy bolters fired somethign like a soda can (2.5"). Not sure but that was what my memory serves.

Certainly looks like heavy bolters fire soda cans.
