Was looking at a box today and the velocity rating was actually less than cheap federal blue box ammo.

Is this stuff just a hyped up gimmick?
At over twice the cost of regular cheap ammo you would think there would be some improvement on performance.

Test barrel length for each of the compared cartridges?
 
The hornady ammo ws 154 gr, the cheap stuff was 150 gr.

Hornady listed the velocity at 3100 fps, according to federal the blue box stuff tests out at 3113 fps.

So i was wondering if the superformance is really that much better? Bullet quality it probably is but is there actually much difference in velocity?
 
It is worth paying more for it as it is quality stuff and certain load like in my wife 243 shoot as good as my handload and myself cant generate that kind of velocity... JP.
 
I've been shooting the superformance 50gr for my 22-250 @ 4000 fps and they've been great, fast and nice tight, consistent groups. Just bought some 180gr SSTs for my 300 win mag; they were rated at 3130 fps (I'm guessing out of a 24" barrel) and I was getting 3230 out of my 26" barrel. They seem to be shooting quite well so far, but pretty hot for factory ammo. I've had good luck with these cartridges so far and plan on sticking with them until I start reloading my own.
 
I have not tried the Superperformance, but i did run some 308 LightMagnum (their previous version of ammo) through a ballistics lab.

I t had an honest extra 200fps at no increased pressure. Each case contained a heavily compressed large charge of slow ball power. About 55gr, as i recall.
 
I chronographed 7mm rem mag superformance gmx last hunting season. Speed was ~120 fps slower than the box said. So the powder they use is either not temp stable and gets slower when it cools off or it's not making what they say it does. Either way I only care about what fps I get in huntig temps (0 to -30) and not what ammo will do on a sunny summer day at +30. I hunt when it's cold. I only use temp stable powders in my reloads.
