|quote = <small>"Bloody Bolters! 'Mass-Reactive Caseless Ammuntion' says it right there in 40k, [[Warhammer 40,000: Rogue Trader|Rogue Trader]], right from the get go: caseless. What do artists always do with boltguns? Cases flying everywhere! Because it looks awesome, alright. Anybody whose seen particularly late 80-90s action movies - 'Dakka-dakka-dakka' brass flying everywhere - knows its one of those things that conveys kinetic violence happening. So when it comes to doing a static image that you're trying to show a guy firing a big rapid fire gun of course an artist is going to reach for having casings flying out of it or it's a heavy battle so there's loads of brass on the ground and things like that, because it's a visual key for people to clue into even subconsciously about what's happening. So actually 'caseless' was useless as a term to describe them because it fought against what the art wanted to do. So eventually we kind of lampshaded it basically, or I did, and wrote in that they use a little kind of like sabot thing to launch them out of the barrel kind of like RPG-7s do. So at that point it's fine, I no longer have to shout at artists whenever I see brass coming out of bolters cause it's fine, we need it, and it looks good."{{Fn|25}}</small>
