Is there any way to use this stuff in a 7-08? Have some left over from when I had a 300 wsm and I'd like to use it up in a 7-08 if possible. Doesn't have to be anything fancy. Just go bang and shoot clays at 100 yards or something for a youngster to learn on.

Hodgdon doesn't list any loads for the 7mm-08 using Superformance powder ! Cast a careful eye on any data you receive from independent sources !

I find it strange that this powder is for only a handful of rounds. Is it that quirky or is Hodgdon behind on working up loads?

Wish I knew "the rest of the story" as Paul Harvey loved to say.

A little while back I asked Hodgon why they showed data for Super Performance in the 6.5 CM but not the .260. IIRC, they said they had an agreement with Hornady to not publish the data unless it provided 75fps velocity more with the same bullet than other propellants.

The burn rate charts show Superformance to be slower than the 4831's. That's going to be too slow for the 7mm-08.

Very interesting info gents. Thanks for the posts.

Wonder how long it going to take for experimenters to work up loads for this powder. A high level hobbyist with pressure testing and chrono capacity should be able to handle the task. One would think there would be more data already on the internet. Superperformance data seems to be a large black hole.

DF

ed. for spelling.

They don't list Leverevoltion (LVR) for the 356 and 358 Winchester either, but LVR shows nice velocity increases in the 338 Federal. Those rounds use similar powders.

I'm assuming they saw no gain with LVR in the 358?

I was wondering the same thing??

I tried Superformance in my 300 WSM and was disappointed with the results. Not nearly as accurate as Big Game and much slower, now it is just another can of powder that will sit on my shelf till the end of my days...

I was thinking of getting some to run in my '06. Perhaps I'll pass and look at some of the Big Game loads or other Ramshot powders for it.

Big Game works great in my 30-06, I had been happy with IMR-4064 pushing Barnes 168 TSX, very accurate (under 1� @ 200 Yards) and 2720 fps BUT a switch to Big Game pushed the speed up to 2906 and groups not as good but still 1� @ 100 yards. Happy with a MOA load that is nearly 200 fps faster!!

I also tried it in my 300 wsm, I was getting higher speed and better accuracy with RL 17.

IIRC,they stated somewhere,that they would only publish data for rounds that showed a significant increase .

Find some Hunter. I use 59.0 grains under a 180 gr NP. Fast and accurate.

Thanks, I'll look around for some. Good info here and I'm glad I bumped into it. Thanks guys.

For the OP ref the 7-08. I owned a 700 CDL in 7-08 that I should have never sold but it went to a kid that needed a good deer rifle. My best performing powders were W760 and Varget. I shot 139's 145's and 160's using those powders and everything was sub MOA in that rifle and the only work to it was adjusting the trigger weight and sear. As far as Superformance in the 7-08 I'm thinking it would be like using RL25, H1000 or similar powder in an '06. You could but it wouldn't be very efficient. You might want to find a buddy that could swap you something more geared to the 7-08 for the superformance.

But, what's the Superperformance good for?

I have a can and not a clue where to use it. If I was sub it for H4831 or RL22, what load would I use? Would I take the three or four published loads and extrapolate the charge for an unlisted round?

Before I try all that, I'll pick up a can of another powder and move on. And as posted earlier, that can of Superperformance will just sit on the shelf.

DF

Well that's kind of where it sits on the burn chat, between H4831 and RL 22 or W780. That venture is up to you if you want to work with it and find a load. It's been done before. I know they use a blend of superformance for the Hornady factory ammo perhaps a call or e-mail to them might yield a usable solution.

I fired Hodgdon an e-mail to see if they have anything for you. I'll let you know if and when they get back to me. Don't light it off as a roman candle just yet

Thanks, sent them one myself.

We'll see what they say.

Seems a shame to have a high tech powder and only publish a hand full of loads.

DF

I gotta believe Superformance would make the 7-08 go bang. It might not be the ideal powder, but if that was what I had, I would load it and shoot it 'til it was gone as long as the results were anywhere near tolerable. I would try it with the heavier slugs, like 160-175gr, as long as your 7-08 will stabilize them (never understood why 7-08 barrels are twisted so slow). I would try magnum primers so as to get the best burn possible. Some guys shoot 4831 in their 45-70s, which isn't exactly what I would consider "efficient." With too-slow powders, at least you know you can't dump too much in the case. So what if it's 50-100 fps slower than the ideal load. Just think positive thoughts as you pull the trigger and the buck will be yours.

Last fall as I was loading ammo for the upcoming seasons,I gave Hodgdons a call to see if I could use Superformance in my 7WSM. The tech I talked with (Mike) told me that I would not work and that there is over 40 blends of Superformance used by Hornady but only one is available to us reloaders. He was quick to caution me about following listed loads as this powder is very very sensitive! So all I loaded was 65 grains in a 30-06 behind a 150 CT BT. Took a nice 4 point buck in area 4 with this load.

I wander what it would do with the Whelen? Their factory loaded 200gr is moving a long at 2900fps. Would like to see it work with a 225 or 250.

I'm guessing I'll get a similar message back from them. Perhaps they ought to offer their superformance powder in a short, standard and magnum action application so folks can get the right one for their particular needs.

I,m going to try some with heavy bullets 145gr or more. I have loaded RL26 using 160 gr Nosler Partitions and

had good luck. I found WLRM primers lowered the SD nicely. Guess I,ll try Superformance with 150gr Nosler Partitions.

After exhaustive research and advice superformance can be used in any cartridge that uses H4831sc. Start 3 grains below your max load of H4831sc and work up to your same load using superformance.
Superformance is slower burning than H4831sc and Reloader 22 but is capable of giving higher velocity in some instances than the original powder. There are however exceptions to this, consult Hogdon manual and Hornaday No10 manuals.
As always reloading can be hazardous so follow ALL PRECAUTIONS.

Works nice in the 3006 165 gr in my 03A3, 03 , & 1917 rifles just follow the data from Hodgon's manual. There are powders that could be more perfect or give greater accuracy and velocity. I don't know. You can spend a fortune searching them out and developing them. I started with a 1 lb bottle to try it. I like it so far and have a 8lb jug it cost me 169+12tax=181÷8= $ 22.60 /lb that's inexpensive shooting in my book. What do you want ,egg in your beer? MB

They show .260 Rem now, but only with 143g bullets and up.

No horse in this race, just an observation, of the several shooting and reloading sites I cruise, I can't help but notice that Superformance is seldom if ever mentioned as anyone's favorite when the word "accuracy" is mentioned. Hmmm.

Historical comment:
When Hornady Light Magnum was first announced, my older brother Bob (chemist and hand loader ) talked to a contact at Hornady and told him that their powder from a 30-06 looked a lot like VV N133 powder. The contact confirmed this and Bob and I switched to N133 for my .308 and his 30-06. Since my loads equaled those of Hornady, I just stopped loading .308 and bought Light Magnum. As LM was phased out, I have switched to Superperformance and stopped wasting time and ammo playing with new hand loads. One 20 round box usually lasts a few years now.

However, I still use N133 when I want to push a new caliber velocities up at pressure lower than other powders. This is usually 10,000 to 12,000 psi lower for same velocity.
An example would be 400 grain hand loads for the 1895 .405 WCF. Velocities up to 2157 have been achieved with pressures safe in the rifle. Ongoing experimentation suggests that 400 grain velocities of 2200 fps can be reached at pressures of the original 300 grain factory loads. This velocity puts our 400 grain .405s up above the Factory Hornady 450/400 ammo at 2050 fps and well into African DG ammo ranges.

These 400 grain Woodleigh bullets do work well on Cape Buffalo:

I,m also working on PP4000mr with WLRM primers Win case Speer 145gr bullets at 2895 FPS Accuracy so so, I add a little

more powder. I have RL26 at 2882 FPS with the Speer 145 gr Bullets WLRM primer Win case. PP400MR using 154 gr Interbond

2698 FPS only 2 shots Lab Radar Quit. Hunter using 140gr Partition Starline case WLRM primer I got 2904 FPS SD of 5.6 of all.

Best I got from Superformnce was 2697 FPS using 139gr Hornady, WLR primer and Starline case. I,ll try one more time and give up

on Superformnce. Worked great in my 270 win and my 30/06.

It was very accurate in 270 Win with 140gr bullets.

Hornady has 7-08 factory loads with Superformance powder. If you're shooting Hornady bullets try contacting them. They may share some load info with you.

Superformance Powder has different blends.Only one was released for handloaders.It only works in specific cartridges.When you see it in cartridges that have no listing for reloading,it is a different blend that has not been released to hand loaders.It might even say this on the powder container.

Ammo makers use all kinds of blends to get pressure and velocity as consistent as possible for a given cartridge load. Trying to chase that is a waste of time and energy since those “blends” are not available to you in the first place and it’s doubtful they’ll share it for liability reasons anyway. Happy tinkering.
