Hornady Releases Superperformance 308 Win Match Cartridge

 
(Grand Island, Neb.) - Hornady® unveils the next generation of match ammunition - the Superformance™ 308 Win 178 gr BTHP Match. Achieving 2,775 feet per second from a SAAMI spec 24" test barrel, this new load is approximately 175 fps FASTER than any comparable commercial load available today! Topped with the NEW 178 gr BTHP Match bullet featuring a .530 ballistic coefficient, this Superformance™ offering provides industry leading ballistic performance.

"The new 178 grain BTHP Match bullet was purpose built, and optimized specifically for the 308 Winchester chamber. It features an aggressive ogive as well as an extremely efficient boat tail that makes this projectile highly effective aerodynamically, yield less wind drift and allows the shooter to obtain flatter trajectories. Accuracy results were excellent. We shot a .680" group at 200 yards with our test equipment, and field tests out to 1250 yards yielded 8 inch, not 8 MOA, but 8 inch total circumferential groups." - Joe Thielen - Hornady Project Engineer


Remaining supersonic to approximately 1,275 yards, this new load provides a 200 to 250 yard advantage over anything else currently available in 308 Winchester. Because Hornady incorporates its Superformance™ technology, there is no increase in pressure, barrel wear or felt recoil. It also offers incredible temperature stability and excellent accuracy potential.

"When we combine this high B.C. match bullet with our Superformance™ propellants, the result is a completely new load specifically designed to maximize every aspect of the 308 Winchester." - Dave Emary - Hornady Senior Ballistician.

Interesting!
I wonder when it's going to be out?

I have some and am going to try it out of my TRG

this load could reshape the .308 market and dethrone Lapua's 155 grain Scenar!

I can't wait to run it in my obr's

Nice,,, but can anyone get it and where, and how much?

That is a higher BC than their 178 AMAX isnt it?

Sounds like a smokin load

with it being made for the 24 inch barrel i have to wander how it will work in the more Std. 20 and 16 inch ARs

Sounds like its loaded to "light mag" specs.   Probably Great in a bolt gun, I'll let you guys test it in a semi.   Sounds hot to me.   No free lunch in physics.

Normal 178 Amax has BC of .495, so this is a little better.

ETA:

More right than I knew,  Hornady discontinues light magnum for new Super performance:
http://www.hornady.com/store/Light-magnum-heavy-magnum/

As most people found, Light Mag in a semi 308 is not such a great idea.   I would not run out and buy a case for my DPSM or OBR quite yet.

Hornady even put a warning right on the light mag boxes "Not for use in semi-auto or gas operated firearms"

However Hornady says Super Perf is ok in semi:
"Superformance provides increased performance, and is safe to use in ALL firearms, including semi-autos, lever gun and pump actions."
http://www.hornady.com/store/Superformance/

Am I going to be able to use this in a 7.62 chambered DPMS?

Interested.  Any word on how it runs in shorter barrels?

Only played with the .243 loading thus far out of my cousin's gun.  Can't attest fps w/o a chrono but recoil was no different and his rifle appeared to like the loading.

That's a heavy bullet. Will it even fit in the DPMS magazine? Anyone have the COAL of this round? I'll try a box in my LR-308, but I'm guessing it will be in the $30+ range/box.

Surprise! It's way less than $24 per 20rd box.

I do want to know what COAL is - any longer than 2.820" and it's not shooting through my SR25EMC...

ok, if it's less than 24 for 20, I might just have to get some

Wow, that's cool. I might even buy TWO boxes

 

I have a few boxes coming and will run them through my 16" and 14.5" barreled .308 ARs. Chrono numbers to follow...

Midway has Hornady SUPERFORMANCE 150 & 165 grain SST ammo listed at $27/20.  I can not imagine the 178 grain boxes being sold for less.

You just need a better imagination...

Check out Powder Valley for HOR8077.

You are correct.  Powder Valley is selling it for "WAY LESS" - $23.27/20  - $0.73 per box less (3%).  Given what Hornady is advertising, it is a good price either way - hopefully it stays that way.

Is the super powder Reloader 17 or the commercial equivalent?

OST

If the cost were $22.25 I would have said way less than $23. It's just semantics and point of view.

I plan on using it in my 20" so when I get some I will let you know. Also my team mate is going to shoot some this weekend and I told him to try some through his 12" POF. Just to get velocity.

[/quote]

How did your teammate do with the new ammo in his short barreled gun last weekend??

Curious minds want to know

Thanks

Finally got a chance to shoot a box of this ammo at the range today.

COAL mic's right at 2.800 and the rounds fit fine in Magpul LR20 mags.

Recoil is very stout in my 16" KAC SR25 Enhanced Match Carbine, but I did not see any pressure signs on the brass, nor was there any problem with feeding or extraction. The Superformance certainly gets your attention when you're used to shooting Hornady 168gr TAP Amax. Also did not notice any untoward flash or blast - although it was right after noon so I probably would not have noticed any flash anyway, not matter how bright.

With a 1:11 chrome lined match barrel, MV was 2545fps (corrected) at standard ISO conditions, 900' ASL. In comparison, the 168gr TAP Amax load was at 2465fps (corrected). Driving a 10gr heavier bullet 80fps faster in a 16" barrel... That's pretty darned good.

If I were trying to shoot 1000 yards from prone, I'd go with the Superformance. If I were shooting 600 yards and in (DM or match carbine type stuff) I'd probably stick with the TAP Amax for faster follow-ups.

Wow.

FYI
I tried a box last week in two rifles.
Rem. 700 20" = average of 2655 fps
Rem. 700 24" = average 2707 fps
Typical measure from 10 feet, average of 10 shot strings.

Sounds like a great load for short barreled guns!

What about accuracy from your 16 in barrel???

I used this ammo in my Remington 700 in 308Win, which has a 18.5" 5R 1:11.25" twist barrel. The target below was from my first range trip with this particular rifle. The range was 200yds, and while a 3 shot group will never be a good indicator of accuracy, overall it performed pretty well. I hope to get more range time in the coming weeks and come up with some solid dope.

Sorry guys, no chronograph here so I have no idea about the MV.

Well, I can tell you this round shoots minute of dirt from my EMC... I was just shooting at the berm for MV, not at paper for groups .

My EMC is typically MOA or better at 100, so I'd expect this Hornady match ammo to shoot very well. I will post accuracy info once I have had a chance to shoot for groups.

Anyone know how these 178gr bullets fair in a 1/12 factory R700P barrel?

I'm very interested to know how they are getting these velocities without pressure problems.  

I get high pressure signs with 44 grains of Varget over the Sierra 175 bullet.  

I'm sure the reloading community would love to be able to use this powder, but it would cut into Hornady's market, so I doubt we will ever see it with data.

So my Hornady manual shows a discounted 178gr HPBT bullet.  Did they just bring this bullet back or is it new as in maybe a different ogive?

I am pretty sure 44 grains is  max for a 168 grain a-max bullet with Varget.  My 308 was very hot with that load a 178 would be bad vert bad.

I wonder if this new powder is the IMR 8208 *Lehprecaan* I keep hearing about!!!!!!!

Good article here on accurateshooter.com


Hornady Manufacturing has just announced its new line of “Superformance” hunting ammunition. Hornady claims that, “across the board” the new Superformance ammo will deliver “100 to 200 fps higher velocities than any other standard ammunition currently available.” Hornady also claims its Superformance ammo delivers increased velocities “WITHOUT increases in felt recoil, muzzle blast, temperature sensitivity, fouling or loss of accuracy.” Hornady President Steve Hornady says this is “a whole new standard in ammunition performance… We are going to be able to raise the velocity of almost any [hunting] load you’ve ever used… by 100-200 fps.” Surprisingly, the marketing materials even claim that Superformance ammo delivers higher velocities with “no increases in barrel wear” — something that runs contrary to common sense.

Rather amazing claims are being made for this new Hornady ammo. Are such claims to be believed? Well, when AccurateShooter.com tested Alliant Reloder 17 powder last year we confirmed that it could deliver 100-200 fps more velocity than most popular powders, in some cartridges. Presumably, Hornady is employing propellants with technologies similar to Reloder 17. Hornady’s marketing materials state that it is using “ultra progressive” “21st Century” propellants for the new Superformance ammo. Hornady has also brought out a line of GMX® mono-metal bullets that feature two deep cannelures for reduced bearing surface. It is well-established that this kind of bullet design can yield higher velocities, particularly in the big-bore calibers with heavy bullets.

So… the velocity claims may be bonafied, though we would expect the velocity gains will vary among the cartridges. Some chamberings will benefit from the new propellants more than others. And only half the Superformance ammo line-up features GMX bullets, the other half being loaded with more conventional SST® bullets.

How about the claims regarding recoil? The claim that Superformance ammo can deliver 100-200 fps more velocity without any more recoil is questionable. Hornady can’t alter the laws of physics. If a bullet of given weight has a higher muzzle velocity, it MUST produce more recoil than the same bullet moving slower — provided that the propellant charge weight (and rifle weight) are held constant. The only way Hornady can achieve higher velocities without increased recoil is by either: 1) reducing bullet weight; or 2) reducing the powder charge (or gas-related recoil). Hornady could hold recoil constant if its new propellants achieve the higher velocities with a reduced powder charge compared to “conventional” loads.

Hornady has issued an 11-page technical report that provides support for many of its marketing claims. Authored by Hornady Senior Ballistician Dave Emary, the report features some interesting test results, summarized in graphs. Regarding the recoil question, Emary argues that “Recoil … has parts to it that are not commonly understood. The fundamental misunderstanding of recoil is that the recoil is over when the bullet leaves the barrel. In truth, the vast majority of recoil occurs after the projectile exits the barrel. By far the greatest percentage of recoil is produced by the force of the gases and propellant residue/ejecta leaving the barrel.” Emary cites test results showing that “approximately 85 – 90% of the recoil happens after the projectile has left the barrel”. If Emary is correct, then Hornady might be able to achieve higher bullet velocities without enhanced recoil, provided the gas-based force is reduced.

I saw these at my local academy yesterday!!

Anyone else have any additional experience with this new ammo in 308???

Thanks

To answer my own question, I found a new article which stated this is new bullet.  They tried to maximize BC for this weight class

can you share the article with us??
