375HH 300 grain DGS @ 2,670 FPS
458 win mag 500 @ 2140

Claimed 100 to 200 FPS advantage in almost all carts.
This is not the light magnum loads but a new propellant

now to call Hornady and order some of that "magic" powder. A ha-ha-ha-ha-a-ha!
Could obammy have been the golden opportunity to keep components out of the hands of us neafrious reloaders who rob the ammo companies of their rightful profits?

i have always loved Hornady bullets and products. unfortunately finding their ammo here in sweden is not easy

Federal has had their "superformance" ammo out for around 4 years now.

Hey Rich

I thought you'd love a load that let the 375HH "finally" keep up with the 375 ruger!!

Yeah . pissers for federal charging TWICE what hornady does? I just love guys that don't look at the whole picture

Federal was pretty selective with their HE offerings.
At first glance Hornady has a far larger selection of cartridges being offered in this category.
It is interesting that their 458 super performance offering is down from 2260 to 2140 FPS.
I did read on a "cheaper than dirt" blog that they are using a completely different powder (mix of 2 powders) than their light magnum and heavy magnum loads that achieves about the same performance with less recoil and less compaction.
Nothing like a little competition bring forth better products and innovation.
Lets see when this stuff hits the shelf. A little late for this season. Perhaps they are gearing up for 2010.

It seems to me that Hornady ammo always has been a good ammo. It mushrooms nice and it kills the animal.

I'll buy Hornady ammunition if I possibly can. I want to support a guy who brings out safari ammo in 450-400, 450 NE, 470 NE 500 NE...for about 1/3rd of what Federal has been charging. He'll get my dollar every time.

What Biebs said! Plus One!

Hornady is really working to offer us variety and performance in big bore cartridges.

From the their website:

"Superformance ammunition is 100 to 200 fps FASTER than any conventional ammunition on the market today, and achieves this performance in EVERY gun, WITHOUT increases in felt recoil, muzzle blast, temperature sensitivity, fouling or loss of accuracy."

Ammo companies have been known to exaggerate some of their achievements. Now Hornady may be on to something here, but the increased energy that is generated by increasing the velocity cannot produce a result with no increase in recoil; that is just not possible. Would love to see independant lab tests.

Is that true?
I was under the impression that:

a)a lighter powder charge would generate less actual recoil for a given velocity than a heavier charge of powder

and

b)since the operative word in the Hornady statement that you quote is felt, a powder with a burn rate and pressure rise different than that of more commonly used powders might lead to a difference in felt recoil.

No?

Yes I agree Thank you Hornady for making those nitro express rounds for so much less and so much better. As a kid I learned while hunting waterfowl that the federal are so much weaker than even a winchester drylock no comparison.

300 gr ---- 2,670 fps ---- 4,750 Lbs/ft-sec
300 gr ---- 2,470 fps ---- 4,065 Lbs/ft-sec
Diff of 14.4% ---------------- 684 Lbs/ft-sec --->

The difference in kinetic energy is substancial.

By comparison consider the difference in recoil between a 30-06 Spr and a 300 Win Mag.
And we know that the differnce in felt recoil is immediately noticeable:

180 gr ---- 2,700 fps ---- 2,914 Lbs/ft-sec
180 gr ---- 2,960 fps ---- 3,503 Lbs/ft-sec
Diff of 20.2% ---------------- 588 Lbs/ft-sec --->

If a difference of 588 Lbs/ft-sec can be felt, then I suppose it is more so with 684 Lbs/ft-sec.

I still believe despite using a different powder with different burning characteristics, that it could still not negate such a substantial difference in energy.

Perhaps Hornady used the word "FELT" recoil in a very loose sense, and is perhaps just that ... LOOSE.

The pity is that no factory for 458 Lott, for I am waiting for Ardesa (Hornady distributor in Spain) and bring ammunition from this factory to my country and I would have liked to try the case in ammunition caliber 458 Lott . One observation, I will not use ammo 458 Winchester Magnum in my rifle caliber 458 Lott safe emergency . So I buy a box and try it on my 375 H & H Magnum and even in my 338 Winchester Magnum. I find it interesting. And finally, is a fairly inexpensive ammunition compared with the European Standard, RWS and the American Federal.

A greeting and good hunting,

Oscar.

Hey Warrior,
How would a difference of 14% be more noticeable than a difference of 20%? Confused again?

I really don't think this ammo is really new
because i've been shooting it at those volocitys
for awhile now.

the velocity isn't -- that there's factory loads for it is

684 Lbs/ft-sec is more to deal with than 588 Lbs/ft-sec.
I am talking "quantum" and not "percentage" if you could rap your head around it.
It is the quantum of energy that does the work, as a measure of work.

driving through the ghetto in my new cadillac
gotta rap my head round this energy attack
quantum mofu quantum mofo that be where its at.

google mofu google mofu google that attack
quantum is the unit Planck gave us way back
Planck be yo daddy when you measure that attack
