Hornady "Superperformance"?

Yes, it is a rebranding of their "Light Magnum" loads...and now they offer a wider range of cartridges, bullet weight and style.

Nope...the 'Superformance' ammo is not the old 'Light Magnum' fodder!

If you look at the poop on this new ammo, you will see that the velocities, energies and the pressures are now LOWER than the old Light Magnum ammo.

This to satisfy the ever expanding use of these cartridges in 'auto loading' (AR) type, and others, rifles...Hornady says the performance is so close to the old LM ammo that the difference is negligible.....

I have used Hornady LM in 7mm-08 for years, launching a 139gr SST at 3000fps...now the new and improved stuff pushes the 139gr SST to 2950...not too bad, I guess, what's 50fps when your plowing? hehehe
 
Are you sure they just didn't publish actual velocities? Light mag was famous for published velocities that were way higher than actual. In fact I've seen some 270 win. Light mags that were hardly faster than standard Federal power shok ammo.

That is what a Hornady phone technician told me....he said that they fine tuned several loads and the Superformance concept replaced the Light Magnum and Heavy Magnum offering....some loads were tweaked, some remained pretty much the same.

The 338 225 gr, SST Superformance, for example, has identical muzzle ballistic than the old Heavy Magnum 225 gr. SP and is still not recommended for use in semi-auto rifles

The tech guy could be wrong, but this is what he told me.

The same technician told me that is still work in progress...so do not mourn the loss of a particular load too soon...:D:D
 
:p Already grabbed enough to tide me over for a few years.
Krochus, the leverevolution stuff does not always stabilize properly in the old 1/38" twist barrels. Also, I like a wide Meplat. :)

according to Hornady, they publish what they have been able to achieve through there own testing....your results may vary!.....according to Hornady....!?!

Yup...that is one of the stories we were told also....bottom line is, the LM line was tweaked to provide Hornady with better and broader sales...if for years your under the impression you cannot use this wonder ammo in your favorite lever gun, then it is changed so you can...most folks still wont bite, all they remember is the old directive NOT to use this in a lever gun, Semi-auto ect...

Change the ammo, now it's safe to use in lever guns, autos ect... and not change the name equals few sales...change the ammo AND the name...everybody will look at it...it is marketing!

Some of the offerings, or I should say 99% of the offerings that used to be LM has been changed...ever so slightly due to the powders used now...but changed none the less.

The 338 225 gr, SST Superformance, for example, has identical muzzle ballistic than the old Heavy Magnum 225 gr. SP and is still not recommended for use in semi-auto rifles

Correct...and the SST load is what...? Moving along at SP (Spire Point) velocities which are SLOWER than SST velocities of the same loadings.

So, the new Superformance moving a SST is the same as the old LM that was moving a SP...! And the SP loadings were always SLOWER than the SST loadings!

This is of no concern really...the performance is still there...only on paper will the velocities and so on be differentiated, real world, no. If you can realize 50 or so fps difference at range...your a better man than most.

So we were told the same as to more loadings on the way....who knows?
 
Yes and no. It seems to be filling the niche that the Light Magnum loads occupied, but some of them have been tweeked slightly. I notice that my favorite antelope load, the 150 grain 30-06 is now listed at 3080 fps rather than the LM rating of 3100. (Who needs a 25-06?)

It would be nice if you could use the new loads in semiautos. I hated always having to remember to ask what kind of rifle the customer had.
 
In reality...IMHO, I don't think the LM's were really 'dangerous' in semi auto's, just that it beat the snot out of the rifle.

I may also add, just speaking with a super good guy from Hornady, that the burn rate, burn curve, pressure curve, powder blends... all that powder guru engineer stuff has been changed so to say...

Smoother, more linear burn and pressure profile resulting in improved accuracy.
