So anyone know what the actual rate of fire for a bolter is? I always think it is semi auto with burst fire but i have read once of it going full auto in the night lords omnibus
Well some art does depict them with gear. (from Forgeworld's Taros book.)The storm bolter was designed as a full auto assault version, so while a bolter may be capable of full auto, it's not its primary purpose. A SMs reflexes and marksmanship married with targeting technologies in their armour mean that one placed shot should be enough for most targets. Besides, with such a small mag capacity, it would be extremely wasteful to go full auto.
I wonder how many rounds a SM would carry into action. Modern troops wear battle vests or chest rigs with anywhere from 300 to 500 rds, plus grenades and other goodies. If a SM was carrying 500 rds of .75 ammo on him, he should be dripping with bandoliers and magazines mag locked to any spare surface.
but i think it is a precision weapon. I mean in many novels i have read it is of the space marines perfectly placing shots with there bolter. Now yes space marines do have fantastic aim, but the weaponry must match thatThe Bolter is not a precision weapon. If it was, it wouldn't have the necessity for an explosive round. It can be used as one, don't get me wrong, but the warhead means it can be used as an area of effect weapon, similar to how the .50 cal or Minimi/GPMG are used today.
They are used against targets in hard cover like rocks or buildings, not because they can punch through the rocks (although the 50.cal with time can probably chew them apart), but because they cause spalling and fragmenting of ammunition. If you've ever thrown something like shale or flint, and you've seen it shatter, then that's what makes it lethal, as well as ricochets, in addition to fragmenting rounds scattering pieces of metal everywhere. Put an explosive charge behind, either on a impact triggered timed delay like the typical bolter ammunition, or airbursting, similar to Metal Storm Ammunition, you've got a recipe for mincemeat.
Fired on full auto, even if the Space Marines cannot directly target their opponents, but know of their position, they can effectively spray and pray.
It's a brief marketing demonstration of its effectiveness, and what is mostly apparent about the XM25's HEAB (high explosive airburst) is that it has an aft-charge, causing fragmentation to targets it has already passed, which means it can do its signature firing into a room and making gibs out of whatever is in there - that's probably the metal storm ammunition type, which going by Codex:Space Marines is limited to "Sternguard" Veterans or "Seeker" Veteran Squads in Legion Crusade List.
Considering the nature of the operations that Astartes undertake, I think that's more of a gameplay balancing factor, and that the Astartes given enough time and information are probably able to requisition more ammunition of this type. I think the only reason the Boltgun ammunition isn't a direct quote of the XM25 HEAB is because a load of geeks in a shed in the black country or the early 80's weren't aware of its existence and their knowledge of weaponry wasn't as well known or availability to research (short of Jane's) was harder to get hold of for up and coming writers.
Edit - in addition to KF, my webbing on deliberate ops took 8 30 round magazines (only loaded 29 though, left the spring springy and reduced stoppages) in addition to the one loaded in my rifle, and I had a daysack which contained a further 300 rounds in magazines and either a 420rnd ammo can or enough for two reloads of the attached fire support group, whether it was the 60mm mortar rounds, spare LASM's, or up to 400 link of either 7.62 or 5.56. Throw in a couple of reloads for the Sig, and two full tracer magazines, and 4-5 grenades, and multiply that between 8 of us. That was a typical load for a deliberate helo-borne operation - fly in, drop between 1-5 clicks, yomp in, drop day sack, fire and maneuvre in, complete objective, and then yomp over to the helo for pick up. The amount of ammunition there was in case the operation went tits up, such as a Chinook or Merlin getting shot down, or there was a redirect to a TiC with T1 casualties en route to pick us up. I've only ever needed that amount of ammunition once, and that was when we pushed too far north nearly into Ghor to avoid an encirclement.
But consider that with Space Marine operations - for example Beta Anph IV saw a Terminator Squad infiltrate a genestealer infested network of prefabs - their ammunition soon began to run dry, and Culln lost 2 to genestealers. It doesn't state how much ammunition was present (and they were using Storm Bolters with obvious full automatic), but simply that there was probably only 6 seconds of ammunition available to the Assault Cannon - which you can assume is roughly analogous to something like a 30mm Avenger (the 7.62 probably was more like the rotor cannon of 30K Legiones), which is around 4200 rpm at full speed - the hopper for the Ass Can was likely around 400.
Their armor/musculature absorbs the recoil and perhaps even the bolter itself has anti-recoil mechanisms at work.but i think it is a precision weapon. I mean in many novels i have read it is of the space marines perfectly placing shots with there bolter. Now yes space marines do have fantastic aim, but the weaponry must match that
Personally I always viewed the bolter as someone going.Being able to be used as such does not a weapon make.
A knife is not a ranged weapon. Sure, it can be thrown. I must have thrown my bayonet thousands of times at a board and got it to stick point first in the throat of a mansized target shape in a board in my room. Doesn't make it a ranged weapon, though.
The Deuce is not a precision weapon by intent, design or use. The bolter, meanwhile, is something that is intended to kill even on a miss - similar to the 50. cal - it is fired at a RoF fast enough, with a wide enough AoE in a cone of effect to wound and suppress enemy light infantry and vehicles that are not coated in sheet metal.
