    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.


  • 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.








  • Yeah, like I said, I will never buy a chevy car again. The transmission carrier bearing is worn out. It is also where the speed sensor is housed. So the speedo drops out any time you are not accelerating. This causes a speed/air/fuel mismatch and kills the car any time you slow down unless you keep it in gear (manual). So if I beak too much on the high way or going up to a red light, the car dies and I quickly have to get it in gear and pop the clutch to jump start it, or awkwardly start turning the key to start it normally while moving.

    The bearing is about 35$. Taking out, disassembling, rebuilding, and reassembling, reinstalling the transmission is over 3500$. The car is worth 4k at best. Not worth it. Apparently this is a known issue with this transmission and replacing the bearing just gets you another 100k till you have to do it again.



  • Rather than just downvoting you, let me explain why you are getting downvoted. It’s because that isn’t true. For-profit healthcare will both want to increase the cost as well as decrease the cost depending on where within the chain they are and where the money comes from. Are you billing the government through medicare/medicaid? Max that shit out and stack codes. Are you the provider trying to claw money from the insurance pool? You are forced to minimize everything or risk being rejected and not paid anything for services already rendered.

    This notion that our for-profit system saves money and is somehow more efficient instantly breaks down the second you compare how much we spend on the same services compared to universal or single payer systems. The USA pays approximately triple per capita for Healthcare while also receiving poorer outcomes on average.

    Not only that, if our system incentivized lower prices, then why is medical tourism a thing that Americans do to other countries? Like going to Canada to buy your prescription drugs or Mexico for dental work?

    If you spent even one minute looking up the cost of American Healthcare compared to other comparable countries, you would have known how false your statement was.



  • Lol. Yes, I understand your comment and agree. But at the same time, when you look at how Todd executed his grand vision of starfield it was a mess of a game that seemed half baked at best. I support new IP’s, but he could have at least finished making the game before calling it ready. This is an AAA studio, not some indy early release.

    And I’m not asking for some absurd release schedule like COD or BF. Skyrim came out in 2011. Fallout 4 came out in 2015 (glossing over the basically-a-multiplayer-mod-for-money of 76 in 2018).

    But if bethesda had some real leadership, they would have pointed out “we have a TV show coming out” and should have also said “we should ride the wave of excitement and have a game ready”. They knew they had a show in development starting in 2020 and didn’t do anything. The show came out in 2024, and they didn’t have anything. It is now 2026, and approaching 2027 and they still have nothing. What a fucking wasted opportunity. At best they will start FO5 in 2027 with a projected release date of 2030, about 6 years after the show released and 15 years after FO4.



  • I know Microsoft gets all the hate for buying them, but I put the blame of bethesda’s recent failures on Todd Howard. He has squandered all the momentum the studio had and just put them into coasting mode. They had the high of releasing fallout 4 and skyrim, then did fuck all but milk them. Sure, fallout 76 happened -and what a failure that was. Then he had his big push for Starfield- and failed not only on the delivery but also the follow through with not addressing any of the fan concerns in the dlc’s. They squandered so many years that should have been spend continuing their two biggest flagships (fallout and elder scrolls) but instead fucked around for well over a decade. Now they are going to put the studio on crunch time for an entire development to try and get back on track and I am calling it now that it is going to show in the final product.

    Edit: I recognize that in my rantings and rebuttals I have omitted Elder Scrolls Online. And I would give credit where credit is due on the success that it was. It is still being worked on after being released all the way back in 2014, and has generated over $2 billion in sales. I would also like to point out how Todd Howard had nothing to do with that one and isn’t on any of its credits…
