There are several models that still have it. When I bought my most recent phone it was one of my personal requirements. I think there were 6 or 7 models to choose from that were all essentially the same as any other modern phone, but had a 3.5 jack. That was a while ago, but there are still some new models rocking it. I use it all the time.
I am guessing the egg-shell foamed enclosure is for the sound, but you probably have a bunch of sound coming from the fan port, nessisary for ventilation. You can cut a lot of the sound but maintain the airflow by cutting an s-shaped ducting spanning the width of the enclosure. The shape will drop the sound, while then ducting keeps the air flowing. I would not recommend any sorts of filters to block the sound because they are a bit too restrictive for an enclosure in your style.
I was really hoping it was real…
The barrels smallest diametral dimension has to smaller than the bullet, otherwise the rifling wouldn’t engage.
Kind of, but not really. The bullet actually slightly expands from heating. At the same time though, if you measured the diameter of a cold barrel and a hot barrel you would get two different measurements. If the cold barrel is too tight of a fit the bullet has an increased chance of lodging when it heats up and expands.
This is why bullets moved towards copper jackets with some sort of other metal center chosen for various justifications. The copper jacket is soft, east to expand into rifling grooves, not hard enough to damage and wear out rifling, and can stretch a little if it gets too tight.
Really, the BIGGEST difference is going to be the casing, chambering, and pressure. It’s like how people talk about 5.56 and .223 being the same. They are the same only at face value of size and chambering, but very different on rated pressures. A rifle rated to shoot .223 should only shoot .223. A rifle rated to shoot 5.56 is rated for a higher pressure and can shoot both.
In the same regard to OP: 9mm, .357, and .38 special may measure the same, but all 3 chamber very differently and have different pressures.
Hell, even 9mm has 9mm luger (parabellum) vs 9mm NATO. it’s the same round/casing, but again, different pressure. A gun that shoots luger (lower pressure) should never shoot nato. But a gun that shoots nato (higher pressure) can shoot both.
It’s also kinda funny how the most common rifle rounds are smaller calibre than 9mm, so if you ignore all the other metrics, most handguns shoot “bigger” bullets than most rifles.
True, but this is also why “stopping power” is then measured in ft-lb (foot-pounds) or joules for metric. Pistols may shoot bigger rounds, but at significantly slower speeds. Less powder for recoil control and less barrel length for pressure build up. The bigger size bullet is a compensation for the smaller gun. A rile with a smaller round has far more energy behind it’s round.
Most under-rated question. Purrfect.
To be fair, solid state batteries went from being a pipe dream, to being only possible in perfect laboratory settings, to the current state of very real and possible -just expensive. And it has done all of this in about a decade. Just give it time.
Oh trust me, as someone who served and still has friends serving, most of them think he is an idiot too. He was kicked out at major for a reason. Even then, major is kind of the natural Peter Principle rank in the military and it takes more than fogging up a mirror to advanced past. He did not.
