Apparently, this the same powder now marketed by Hodgdon, which Hornady is using in their Hornady Superformance factory ammo.

FWIW, I was over on the "shootingtimes" site parusing the video section and came across a 3 min 21 sec video entitled "Hornady Superformance." In that video, using std factory 270 Win ammo, several shots fired over a chrony averaged 2888 fps. Then using that same 270 Win rifle, the Superformance ammo
gave an average of 3075 fps. A 187 fps increase.

Then, I go over to the Hodgdon site and see this new Superperformance powder added to their loading data for only certain cartridges. As an example, the 300 WSM from a 24" barrel using max loading of this new stuff, averaged 3410 fps using a 150 gr bullet and 3274 fps using a 165 gr bullet. Hmmm!

Then, I thought I`d cruise on over to the Hornady site to learn more if possible. In the "news" section under new products, I stumbled across and downloaded an extensive article by Dave Emary (the senior Hornady ballisitics wizard), which thoroughly explains the hows and the whys of this new powder. The direct link if anyone wishes to read that is.....www.hornady.com/assets/files/superformance-technology.pdf..........

In a nutshell and paraphrasing, this powder upon ignition, completely burns up sooner than all other powders before the bullet exits the barrel, allowing more gases under pressure to push the bullet, hence more velocity, and upon exit there is reduced muzzle blast as well...Hmmmm! Also in the Emary article as you`ll read, they cut down a 300 Win Mag barrel to 20" and discovered that actual velocity losses in terms of "fps per inch", were substantially less (1/3rd to 1/2) vs all other powders tested.....Hmmmm! As a shorter barreled compact rifle fan, this new stuff really has my attention now. Higher MV (as if I really need them) with less muzzle blast too.....HMMMMMM!

I`ve read a few posts regarding some lot to lot velocity inconsistencies with RL17 and in various weather conditions. It looks like this new powder from Hornady and Hodgdon, may have even better performance in certain rounds than does RL17, and may be more consistent and just as accurate as well.

"IF" this new Superperformance powder holds true to form in terms of MV comparisons with two other 24" 300 WSMs I chrony tested vs my 16.5" 300 WSM Ruger compact using a wide variety identical handloads with other powders, then as before, there should only be a 4.5% to 5% total reduction in MV.

3410 fps (24" bbl per Hodgdon) x 95% to 95.5% = 3239 and 3256 fps respectively for a 150 grainer.
3274 fps (24" bbl per Hodgdon) X 95% to 95.5% = 3110 and 3127 fps respectively for a 165 grainer.

And the hi-flying Berger hunting VLDs which I have used with great hunting success, have a little less bearing surface against the bore too.....HMMMMMMM!

From a 16.5" barrel and with less muzzle blast too?...Oh boy!...Gotta get my hands on this new stuff. You 270 Win should try this new stuff too!
From a 20" bbl`d 375 Ruger?........HMMMMMMMMM! Wheels are a spinnin.

When RL17 came along, my shorty barrel grew longer. With this new hi tech stuff, she may get a little longer even yet.
Leave things to good `ol Hornady to come with some really good stuff.

We are living in the golden age of ballistics. I am not a prophet, but I'll predict that we will see even more exciting developments in powders and bullets, and perhaps even in primers during the coming decade. Hang onto your hats.

Man, it is hard to believe it can get better! We have so many options now it is mind boggling! I like it, but man, there is only so much time in the day! Good luck, looking forward to hearing about this new powder.

I see they also have Leverevolution powder also! That might be a good one in the 358 Win?

I just looked at some of their data, they give 3700+ with a 60gr bullet in a 22-250! That is smoking, that could be something with the 60gr PT's in the 22-250! Man, that is like lightening and would hit coyotes or even wolves like a TRUCK! Scotty

Let us hope it works. Save up money for full load re-development gents, if it works!!!!!!

from what i read it should be awesome for 2 calibers i load for 260 rem and 7 wsm
i might start reloading for my 30-30 also,and give this leverevolution a try

Looks to be an interesting powder.

Links?

.................................You can go over to the "24 Hour Campfire" site and do a search. I have read several posts over there by those who had large disparities in velocities from one RL17 lot to the next using the same charge and bullet, and alot of velocity disparity as well going from hotter to much colder weather also using the same RL17 charge and bullet.

As I understand it, RL17 is supposed to be in-sensative to temp extremes....................Maybe not.

In any event and according to the velocity #s I`m reading from Hodgdon, I don`t recall RL17 (see Alliant`s site) doing quite as well in terms of speed, like this new Superperformance powder in certain rounds. The 300 WSM happens to be a good example as well as the 270 Win.

I have little doubt, that Hornady/Hodgdon is marketing this powder to compete with Alliant`s RL17.

where are you finding data on hodgdons web site. when I go to data reloading center and search 30-06, 270 win, and 300 win mag I don't see superformance as a powder. I do see LVR under 30-30.

After posting this I found it.. wow what a limited list of cartridges. 22-250, 243,6mm rem, the wssm family, 300rcm

barthowes,

This PDF gives data generated for both the SuperFormance and the LeverEvolution powders.

Here is the site for alliant reloder 17 recipes.

http://www.alliantpowder.com/reloaders/ ... owderid=25

They look comparable, similar weights in bullets running within 50 fps of each other.
That kind of difference is pretty standard just changing rifles, primers, brass or bullets.
The temperature issue we will have to see.

I bet it will be like comparing reloder 15 and
the various 4895's. Some will work best for some rifles, others for others.

I don't see a search function for the forums at 24 hour campfire.

......................If the above link doesn`t work for you, like it didn`t work for me, then go back to......24hourcampfire.com......from there click "Campfire Forums"......Then scroll down to the "Reloading" section and click onto "Big Game Rifles"......Then scroll down to the thread titled,,,,,,,,"RL17 Temp Sensative?"

You can still read the forums without being a member.

I notice the powders are spherical. Perhaps not part of the extreme line then.

Maybe they will be similar to Alliants Power Pro line.

need SP powder data for the 300 Win Mag with 180gr.
