If you reload AND cast bullets, casting .308” size bullets is a helluva lot easier. It’s easier to size the bullet, easier, to powder coat, and easier to handle the .308 projectiles, to get them started on the case mouths.
Now, I haven’t done this myself….but you can get fired 5.56 blanks… brass cases… super cheap. Then cut them down and turn them into .300BO cases. It makes for cheap shooting.  The other thing you can do with powder coated cast bullets is if the different weight projectiles have a similar profile, you can color code the lightweight super sonic bullets green. The heavier subs you can powder coat red.  Attached File |

Quote HistoryQuoted: TLDW Don't believe all the hype about Big Black bullets. The skinny ones are just as good if not a little better for most situations.  .300 ammo is dropping to the same fifty cent a round rate as the 55 grain .223, and cheaper than 5.56. Comparing the scoped 5.56 with the .300 he had for range seemed kinda cheap for somebody who bleeds Gucci. Micah looking up military max effective ranges for the .300 made me raise an eyebrow. Back in 1977, 460m was what they taught us the maximum effective range was for a 20" M16 firing 55gr ball. |

For the most part I’m a fan of GT videos, but this one missed the mark for me.
I’m a fan of 5.56, 300 Blackout, and 6.5 Manbun. All have use cases I appreciate. And perhaps the best part is that the rifles I have so chambered go bang when I pull the trigger. |

Quote HistoryQuoted: Stupid video is stupid. "I wonder how comparing sub sonic to super sonic will turn out?"  The niche thing that .300BLK does is have decent ballistics in a sub 10" barrel so it still has a short OAL with a suppressor. I normally like his videos, but this one is dumb. He can hit shit at 300 yards without magnification and doesn't understand basic ballistics. The dunking that gets done on the .300blk in some circles approaches orange cartridge bad levels. As a generic troopie round, 5.56 is probably the one to have, for commonality sake if nothing else. That doesn't make .300 useless. I'm not a toothless Arab dirt farmer, so I can afford to have more than 1 gun. |

So what you're saying it 556 sig rattlers are back on the menu?
Because I've been hearing for years that 556 through a 5.5" barrel is nothing but a flash bang, and 300blk is necessary to maximize effectiveness of the platform. But now we're all sure that 556 is better than 300blk across the board and 300blk is a useless round? |

Compare 10.5 to 10.5, and the 5.56 is still better. Apples to apples, 5.56 subs are significantly more stupid. About 1/3 of the energy and the gun probably has to be manually cycled. But subs are just a range toy factor for most people, 99% of the time. From the bold, it looks like we are in agreement. As far as short barreled rifles go, .300 is better at being an effective short barreled gun. In a shorter than 10" barrel, 5.56 sucks and .300 doesn't. Some would say well it's just 2.5" so no big deal... Well the 8" .300 is pretty well tamed by a K can. The 10" 5.56 not so much. So now we are up to 4-5" shorter. That matters. So yeah, the two reasons that people buy .300 Blackout (short configuration and / or subs) it does significantly better than 5.56. And for 5.56 to get the slightest edge in a 10" you have to buy the expensive heavier ammo loads... Which sorta defeats one of the main advantages of 5.56, cheaper ammo. That was another moment where GT showed his ass in the video. The way he described M193 as junk ammo is hilariously misinformed. It's great when used at the right velocity, as his own gel test in the video shows. |

But. Wasn’t he comparing the premier 5.56 round (mk262) to two of the worst loadings in 300, 220subs and 120 somethings? Where’s the 110 ttsx Barnes load? Yes I know he followed up with cheap 55 vs 220. But best load vs best load may have turned out different. And that’s coming from a dude with 2x 300 uppers and still isn’t convinced. |

It’s a compromise, like everything unfortunately.
If you remove the desire for quietness, there are better rounds. If you keep a desire for quietness, but ditch wanting to be able to use standard AR stuff, there are better rounds. Compromising is gay, but unavoidable. Really has been some cool advancements with cartridges geared to short barrels since the original rubber horseshoe brace that Sig sold. Hopefully we’ll get a bunch more advancements in the next decade with cartridges geared towards short barrels. |

I use it primarily to hunt pigs and varmints. I get the hate with some of the claims people make, but I've found that most folks doing the hating either haven't fired it much, or at all, or don't really have a use case for it. |

Sub-10” barrels, and they’re more effective than 5.56, even through light/intermediate barriers, and can use subs for peak suppressed use. Seriously, hearing safe and stupid quiet past 25 yards, or through any kind of sound barrier, with the ability to load supers for a nominal 300 yard effective range out of a carbine smaller than a CQBR. The only thing making it unappealing is the price, and barriers to entry, those mostly being the NFA faggotry, because without a suppressor, there’s very little reason to go with 300 over 5.56 |
