Small-Scale Question Sunday for December 10, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Yes, you can get a .308 with a ten inch barrel, but it's more regulated and it is going to be LOUD, and throw a fifteen foot fireball when you shoot it.

I understand my initial comment might be slightly unclear on the point, but I meant 10" AR-15s chambered in 5.56 or thereabouts. That barrel length in 7.62 is a disaster. I mean, you might as well concuss your enemy to death instead of shooting him.

First, it's low power, essentially a pistol cartridge when suppressed. Second, suppressors are expensive and the legal process is lengthy. You can build or buy "solvent trap" cans, but those are on the police radar and they don't work nearly as well as proper cans. Third, even in the best case scenario, the noise is still significant and noticeable. We're talking 130 decibels roughly, and there is a phenomenon known as "first round pop", where the first shot in a cold can is louder than the subsequent ones. It's not hearing safe, the "whisper quiet" is more likely noticeably louder than a stadium rock concert or a jet aircraft.

Isn't .300 AAC a relative chonker of a round? I can't see how one can call it pistol tier even if it's subsonic. I expect the lethal range will be significant enough that an adversary with a handgun will be powerless to respond.

Take it from someone who has a built-out suppressed.300, I wouldn't recommend it for an assassination.

I have seen claims of around 120 dB from other owners, but close enough, and it's still a 30 dB drop from unsuppressed.

I am under the impression that matters, a lot, because it potentially changes the overall sound signature enough to confuse people who would immediately jump to "gunshot", and at least by the time the round reaches the target it becomes exceedingly difficult to triangulate the shooter, even if it's not Hollywood-quiet.

With common subsonic rounds necessary for suppression, the ballistics are pretty comparable to the .45 ACP (or 10mm), a 220 grain projectile at 1k fps vs a 230 at 900. Of course, the downrange accuracy is much better, but in terms of power, we're in the same ballpark. You're not getting rifle damage at subsonic velocities.

Getting pinged at by a regular scoped PCC from some rooftop inside +/- a hundred yards sounds like a pretty bad time though -- I think it's mostly the honour culture aspect combined with gang-bangers having limited knowledge of modern gun culture/tech that stops this from being on the table.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
