Hornady SuperPerformance 5.56

[tb1911]

I've been testing accuracy/reliability of various 5.56 rounds. Hornady's SuperPerformance 5.56 round with the 75 grain bullet was extremely accurate for me and the velocity compared to other rounds is up there.

Any testing done yet to determine it terminal performance? Any blind barrier testing done that you can share?

Do we know enough to say that it is potentially a good round for duty/defense use?

From what Ive seen this ammo is crap. Molon tested and found it to be woefully inaccurate compared to TAP, other peoples results seem to mirror his. Not to mention it was designed for rifle length gas systems and causes overpressure in carbines, ammo that can cause reliability issues would not be a good idea for a duty/defense load.

As for terminal effects it uses the same 75gr T2 bullet found in 5.56 TAP T2.

Are you sure about this? The whole reason they wouldn't release TAP T2 to the GP was because they thought this round (T2) should be "reserved for law enforcement only"...why would they start production of a whole "new round" and throw on the T2 projectile instead of just increasing production of the proven 5.56 TAP T2? :confused:

Yes I am sure. The original 5.56 performance loads used the T1 then they switched to the T2. For whatever insane reason why hornady decided to release this crap ammo to the civilian market while there exists a venerable black market for 5.56 TAP T2 is beyond me.

I may be missing something, but if this is the same T2 projectile, then why is this so inaccurate compared to TAP T2? T2, from my understanding, is VERY accurate.

If they did switch to the T2 likely because a lot of people were getting horrible accuracy with the 5.56SP. I was getting 3-4MOA at 100 yards with the stuff when other comparable ammunition was .8-2.5MOA (5-6 different loads in 2 different precision uppers). Even the .223SP was shooting around half as big of groups.



I was emailing Jason Hornady and one of their engineers about it but not recently.

So maybe a change to improve accuracy? I only fired one box of the stuff. I should try more.

I ama shooting it in an ACR with a 14.5" barrel.
