Anyone tried this new Black line of Hornady ammo? Thoughts? Man in video states 6-7db quieter through a suppressor and 15-20% reduction in temp input into the suppressor.
Excerpt from Hornady site: "5.56 Nato 75 gr InterLock® HD SBR™ Black is designed specifically for 10.5"-11.5" SBR’s by using proprietary propellant technology and a bullet designed with technology from industry leading Critical Duty® FlexLock® bullets. This round provides exceptional ammunition performance in SBR’s suppressed or unsuppressed, with virtually no flash or residue, dramatically reduced sound signature, will not foul or overheat suppressors, uniform velocity and accuracy, and provides controllable rate of fire in automatic platforms. Designed to meet the requirements of the FBI protocol, this round is the optimum choice for 10.5"-11.5" barreled 5.56 rifles." Hornady® BLACK™ Ammunition 5.56 75gr. InterLock® HD SBR™ & 300 Blackout 208gr. A-MAX® |

Lack of responses on this doesn't inspire confidence View Quote I think that it's more an issue of this ammo being new and relatively few people use their SBR's for HD. (I do). If I weren't already fully stocked with BH 55 gr. TSX and Hornady 55 gr. GMX, I would probably give it a serious look. |

Spoke with Hornady about their companion to the 5.56 load, the 300 Blackout round, stock No. 30731.
It actually now uses their 208gr. ELD Match bullet (not the discontinued Amax), and, like the 75gr. 5.56 load, is designed specifically for defensive anti-personal use. The ELD Match bullet design is the same as the Amax, except now with the higher temperature bullet tip. Neither load is recommended for hunting game. |

Thought why not a buy a couple boxes to test but the 75gr 5.56 Interlock is not available anywhere that I looked.

Look at the velocity, it's nearly 1000fps slower than normal. They use a faster burning powder to help. Slower bullets with faster powder means much less pressure when the bullet leaves the muzzle and much less flash/noise. The difference can be dramatic. But you lose energy - that stuff has way lower energy than standard ammo.

Apples to oranges but I can see it. I have some speer 64gr gold dots that my 10.3 loves but have not chrono'ed it yet. Again apples to oranges but I will compare at some point to take up a few hours of down time. |

Fwiw, I'll point out that energy figures are derived using the square of velocity, which can have the effect of distorting the perception of how the load would perform vs. a load with a lighter bullet, which loaded to the same pressure with an appropriate powder will have greater velocity. Momentum calculations do not use the square of velocity and make similar expanding, and sometimes non-expanding, heavy vs. light bullet comparisons more rational, at least IMO.
I will have to try a box of this ammo, a 6-7db reduction suppressed would be significant. JPK |

I had heard about this ammo, but not about the db reduction in the 5.56 load. I intended to check it out before, but now I really want to.

[#13]
Looking forward to trying some of this stuff. Wondering how the 75 gr bullet will stabilize in a 10.5" SBR with 1-9 twist. I stabilize 55's and 62 grainers with no problems.

Up to now, 2 technological areas have mostly been left out of the suppressor game:
- specialized ammunition and modifications to the gun itself (including action noise). There is a lot of room for improvement and R&D. Exceptions include: proprietary bolt carriers, 9mm ammo with 158 and 160grn bullets, 22 subsonic, and alternative recoil springs (ie JP). If the ammo companies put effort into it, we could see much quieter ammo on the market soon. |

I'm going to try and find this in the next week or so and test it out.

BTW, it was OOS so I set up an email alert. I received the email, but did not order fast enough. I ended up successfully repeating the process. Seems like they get some in and it sells out fast... |

I'm not sure if this is actually a new round or just new packaging for their TAP round... 75 gr. TAP® SBR - Item No. 81295
Either way, I am very interested. I'm just happy to see more SD ammo options designed for 10.5-11.5" SBR's. The lower DB's is just as added bonus and TS-USA's price isn't bad compared to most other equivalent rounds. I wonder why they went so heavy with the bullet? Most other SP's tend to stay in the 62-63gr range? View Quote Not the same round. Your link is for the BTHP round = item # 80267. The SBR round is an Interlock (Softpoint) bullet = Item # 81296. Midway doesn't have the SBR round in stock and even if they did (at their current sale price of $17.29/20rds) TS-USA's price is still cheaper with shipping. I think I may order a case but it will be a while before I can test it. |

The A-Max had an orange tip and the ELD-M has a red tip that is not bright red but semi-dark red. Hard to explain but it should be clear when looking at them. |

I don't see how they're going to reduce the noise other than reducing the velocity. I don't buy it.

If you have full or nearly full burn in the 10.5"-11.5" barrels the ammo was designed for so no combustion is occurring in the suppressor, it seems rational to me that the suppressor would perform better noise reduction wise. Fwiw, I used ammo with a faster than typical burn rate powder to tame muzzle blast in my kids' short barrel 243. It worked, and the ammo was much more pleasant to shoot than off the shelf ammo, even with plugs and muffs for both. JPK |

Quoted:
The tips of the new 300 Blackout Hornady Black ammo is oragneish, not a deep red, so I guess it does still use the older A-MAX bullet. View Quote I checked back, and was told that some of the early production used the Amax, until they could switch to the new bullet. But, the ammo performance is exactly the same. The only difference is the higher temp/different color tip, and the higher temperature hype is a zero issue until you get up into the 22-250 and faster velocities. |

A few days ago, we did non-suppressed sound levels on this ammunition compared to standard M855 using a MK-18 (10.5"barrel). Meter was the LD 800B, C-weighting. At the reference location (1 m left of the muzzle), the difference was slightly under 2 dB; at the shooter's left ear, it was slightly under 3 dB reduction.
Although there were no feeding/cycling issues, this ammo dis not kick the bolt back quite far enough to engage the empty mag hold-open while there were no issues with M855. |

Adjustable gas block? Setting if so?
Barrel orifice? 3db unsuppressed seems significant. JPK |

So I'm just finding out about this tonight, but I knew about the older Hornady SBR line.
I'm looking for a round better suited for SBR's, but that works as well or better than M193 for general use and not just HD/CQB. The other Hornady stuff dropped like a freaking rock and was way down there at 300yd. Any more info on this stuff? Or better options for the 10.5" lover? (nonsuppressed) |

I wonder if this ammunition is harder on your bolt and rifling. Sounds to me like faster burning powder would do that.
Provided that it cycles reliably, and has some sort of expanding bullet... this would make for excellent home defense ammo. |

I picked up a box of this a few weeks ago. Best performing factory ammo I've bought so far in my rifle. First 5 round group was sub MOA with my 18" PSA .223 Wylde stainless.
I ran the last 10 rounds I had through my rugged razor and it did seem a little quieter than the other ammo I was shooting. That was just by ear. Nothing scientific. The PPU 75g match i tried was noticeably louder than all the other ammo I shot through my can. And grouped the worse. |

Not sure if it helps.
But I have some 75 Grain Hornady BTHP TAP. It is significantly quieter, has less flash, and concussion from an 10.5" barrel vs other ammo. The 10.5" with the ammo felt no worse than my pinned 14.5" upper with regular range ammo (55 grain) dd I don't exactly doubt it. I think some of the newer 75 Grain ammo they made for SBRs uses a faster burning powder. https://www.budsgunshop.com/catalog/product_info.php/products_id/411555443/Special+Deals/Qualified+Professional+Discounts/QP+Ammunition/Hornady+80265LE+223+Rem+75gr+BTHP+TAP+20ct |
