IMHO the military should have just upgraded the general use ammo to 70+ grain bullets at 5.56 pressures and rolled with it.

I've shot 45 to 69gr 223 but never 77. I hear they are great for long distance accuracy. Can they load from a magazine? IIC years ago I was told 77 were too long for that.

Ummmmm, do you guys not know that AAC/PSA has been selling 77gr TMK's for sometime now? As I'm posting this, they are in stock. $16.99 a box ($0.85/rnd). https://palmettostatearmory.com/aac-5-56-nato-77-grain-sierra-tmk-20rd-box-ammunition.html Lots of discussions about this ammo in the Ammunition forum. |

77 gr is king, but the 75gr Hornady BTHPs are damn close and a lot cheaper when reloading. 75gr are fine for 3 gun out to 600 yards. For x ring type shooting, 77 all day long.

By your logic a bow and arrow or spear won’t kill a deer because it doesn’t have enough foot pounds to do so. Actually read the thread, not just a few posts. Funny how you mention BC as that’s leading right into why these projectiles work better than traditional hunting bullets. And yes, as shown multiple, multiple times in that thread. .223 fucks above its class with heavy for caliber, high BC match bullets. There is even a cheat sheet on the top of page one for you if reading isn’t your thing. But the real technical stuff involving BC and bullet construction you’ll actually have to read a bit to find. |

75’s and 77’s do good work. If it’s a distance thing just step into the 308 AR world. It’s not expensive anymore.

It all depends on how far you're shooting, what your precision expectations are, and how much you want to spend.
There's a reason match bullets and ammunition cost more. If you never intend to shoot past 200 yards and you want tiny groups you can put fast 50-55 grain benchrest bullets into bug-holes. If you want to ensure you cover out to 300 try Sierra 69s. If you want to consistently hit man-size targets without lots of work try 73s to 77s. There's no free lunch. 55 and 62 FMJ Ball will go bang and hit big targets to 300. You'll have to work harder to hit little targets or not get blown around too much by wind to 400. |

Energy is a useful predictor of what might happen when bone is encountered. I'm not obsessed with exit wounds but I do appreciate them. I had a very hard time getting exit wounds on 200lbs deer. If they don't strike bone they would get caught by the offside hide. The tmk is a good bullet but it's also not great from a 20" barrel inside 50 yards. |

I guess in some weird contrived scenario, I’d shoot an elk or moose in the throat with a TMK and expect it to perform fine. But that’s really just because it’s easy to kill things in general when they’re shot in the throat, let alone with any rifle round.
It’s also almost the last way I’d prefer to carry out the task of big game hunting too short of just squaring up and fighting the moose lol there are so many better cartridges and projectiles to be selecting from for this that it’s silly to even entertain the hypothetical. |

I have other ARs but the only one I have shot for years is my JP PSC-11 rifle with a 1:8" twist. I reload with REDDING Type S Match Bushing Full Dies on a Dillon press. It hates 55gr. and below. As you go up the scale it gets more and more happy. Shooting 69gr. and 75 gr are impressive but with 77gr. match it truly shines. I can produce .330" groups with it. It really is in a higher class. I have a lot of fun pushing myself to shoot as well as my rifle. The rifle has top charging and side charging systems. A trip to the range and you will never use the top charging system again. It is the most useless thing on my rifle.

55g for practice and all around range use.
62g soft point bonded core for CQ, ideal with SBR’s. 77g gives the AR longer legs, makes it effective out to 600 yards. Really shines in an 18” barrel with 1/8 twist. M855 is great for trading for any of the three above or for demonstrating shitty accuracy. |

Pricewise?
I flinch and shake when I see the price on a box of 77 gr. |
