Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Some of these are wrong.

Tracing a call is instant. It took longer back in the days when there were physical switches, but that's been a long, long time ago.

Silencers can make a gun nearly as quiet as the movies, in limited cases. Something like a subsonic .22 will be about as lout as a golf clap. A 5.56x45mm rifle will be hearing-safe, but only barely; it's still going to be very loud, and will def. sound like a rifle.

You can shoot some locks off. You're not shooting through the shackle, you're disrupting the locking mechanism that keeps the shackle closed. It's still unsafe; you're going to have ricochet and spall going everywhere.

To add to this a bit more:

Generally, if you want to shoot a lock (or door frame hinges) off, you use a shotgun with special breaching rounds.

Various forms of these have been and still are used by various Militaries, but more often SWAT or equivalent type units.

The general video gamey / movie portrayal of how this works is usually wildly exaggerated / inaccurate though, usually with pistols at moderate ranges.

Conceivably you might also be able take a door lock/hinges apart with an anti materiel rifle, but this would be wildly impractical.

[–] HelixDab2@lemm.ee 2 points 3 months ago

If hinges are on the outside, in most cases you can just pull the pins out with pliers. Or a small hammer and a screwdriver to act as a drive punch. That's why most exterior doors swing in (hinges on the inside) rather than out.

It's gonna depend on the lock, too. Most locks most people buy are gonna have shit build quality. Some literally so bad that you could just shoot straight through it and not just disrupting the locking mechanism (in the way that some quite a bit stronger locks can be disrupted with, for example, a rubber mallet) but literally destroying it. Others (a minority) might be so strong that a typical gun has no effect at all and the infographic actually gets it right.

Pretty sure chloroform is wrong too.

Chem teacher had some and one kid stupidly took a whiff. She dropped like a sack of potatoes. She woke up in a few seconds but yeah - that shit was instant.

I guess it might take 5 minutes to get enough to be out for a few hours.

[–] HelixDab2@lemm.ee 3 points 3 months ago

Here's what I can find that gives a better answer. Above 100ppm, you'll rapidly start feeling dizzy. But chloroform is also highly volatile, so you would need to have a rag soaked in chloroform just before attacking someone, rather than lying in wait for a few minutes to a few hours. Plus, if you get that concentration too high, you can accidentally kill someone.

So if you'd been hiding in someone's car for 10 minutes, that rag might have lost enough efficacy that it would take a few minutes. Alternatively, if the person in the backseat doused the rag just before attacking the driver, it might be nearly instant.

Supersonic bullet still makes a crack. When you fire subsonic you can get just the sound of the metal bits hitting each other. Whoever is interested look up what an MP5S with subsonic ammo in a firing range sounds like (the S is important in this search)

[–] HelixDab2@lemm.ee 2 points 3 months ago

It's still louder than just the bolt cycling; you're hearing the gas escaping at high speed, but subsonic ammunition through a silencer is definitely significantly quieter than supersonic ammunition. One of the very, very few positive things about .45 AARP is that it's always subsonic, so it's easy to get it very quiet, as long as you have the slide locked so that it doesn't cycle. (IIRC Knights Armament Corp made a .45 for SOF that had a locking slide.) Videos aren't great for hearing what a silenced firearm really sounds like due to the way that most microphones compress sound; they end up sounding very different IRL.

I've been at the range when some other people were testing out a night-fighter rig with .300 AAC and a silencer; it sounded like they were shooting a .22.

I'd love to get a silencer for my Ruger Mk. IV, because that's one that will get very, very quiet with subsonic ammunition. I also want to get a silencer for my AR-15, mostly because that sharply reduces the amount of smoke you have to deal with at night matches.
