Range Report: Hornady 5.56mm 75 Grain TAP SBR

[Molon]

Just the facts, guy, sorry.

The ammo was specifically manufactured and designed for SBRs.

Your tests did not show what it can do out of a SBR.

I'm sorry you wasted your time and money on it.

So you don't have anything of value to contribute to this site. Got it.

Molon,
Thanks for posting this info. My agency has several 14.5" SBRs and one of the LE distributers has been pushing TAP. It will be nice to know a bit about what he's selling the next time he comes around.

Really hoping to see some gel tests in the future.

Word to the wise. Stop your nonsense.

First, thank you Molon, for another excellent post... I'm a fan.

I'd love to see some gel tests out of a 10.5 or something.

Let's see you spend some of your money, your time, your equipment and your energy...

Schmalkald is a troll, but I'm also curious as to how this would do out of a shorter barrel (14.5"?). My ARs are both 14.5", and my vague sense is that much of the powder charge is just burning as muzzle flash. If Hornady is loading faster burning powder for shorter barrels, then maybe that pays off in more velocity and less flash.

So, I can get some of it, then I'll compare this to the other 75/77gr loads that I have on hand, and I'll run them all over a chronograph...

Does anyone know who has this in stock?

I'm kinda weird about the somewhat "flat" tip on these rounds. I remember getting a bunch of the surplus LE soft point bullets from Wideners a few years back... and they choked up a few of our guns... and created a mess when the powder puked all over the barrel extension and chamber, etc.

I'm sure that these hornaday rounds don't do that, but ever since that experience, I'm nervous about any bullet that lacks a "ball" shape at the meplat.

Trying to figure out what powder they are using. Any ideas?

Interesting, Andrew was getting higher velocity out his 11.5" SBR with 75gr Gold Dot. You would think an SBR specific load would yield higher velocity than its competitor out of, well, an SBR. Speer 75 gr Gold Dot isn't even advertised as an SBR specific load.

Devils Advocate: I am hoping the SBR load bullet is specifically designed to expand at lower working velocities. And maybe they chose the powder so that blast and concussion would be less with this load. Dunno.

If you look at their "Black" SBR ammo, they claim 2321 fps with an 11.5" barrel. I wonder if during development of the above SBR load, they realized they can market it to suppressor folks since it was less blasty.

I kinda want to try the Black SBR suppressed 5.56 and see if I can notice a difference in sound. Probably not.
