I bought a Ruger American in 7mm08 and stocking up on different ammo I went to the range. What I had was Winchester super X, Remington Core Lock, Federal Premium all 140 grain and 139 grain Hornady Superperformance. The Winchester shot 15/16 inch ; Remington 1 1/16;Federal 1 1/4 and Hornady a solid 3 inchs at a hundred yards. Quit a difference from the others. Any one with similar experience with this ammo?

Never shot any.
I reload everything I shoot.
But you were supposed to be awed by the Super-Performance advertised velocity.
Not the Super-Performance accuracy!!

I have fired SF ammo in 7mm-08 out of Savage and Remington rifles. It is pretty good ammunition for me and groups well, roughly an inch at 100. Just not something you use everyday at the range because of the price.
I reload as well;but, am new to the 7mm08 so I needed the brass.I was very supprised at the poor results from this ammo;and,that was from 2 boxes.It was $4.00 a box cheaper than the Super X.I think I can live without the extra 200 fps.

Quite often the most accurate load in a given rifle is not the fastest. sometimes the starting powder charge is the most accurate. so this fast superformance ammo is not surprisingly the poorest grouping ammo of the batch you tried. IN my 7mm08 TC venture 42.5 grains of IMR 4064 is most accurate with 140 g Rem Corelocts. this is not the max load!

I agree completely with the minimum loads being most accurate. I prefer minimum loads myself. I don't think I gain any benefit from the hotter loads in my situation since all my hunting shots are well in a hundred yards. Less wear and tear on the gun as well. I'll certainly try your pet load.
My handloads that are right at, or slightly under max loads have always been the most accurate. The key is to fill up the case with slightly compressed loads. If powder has room to move around inside the case you get inconsistent powder burn.
I've tried the Superformance ammo in my 308 and 30-06. The 30-06 loads in my guns chronographed slower advertised speeds, but still faster than most factroy loads. My handloads were faster. Accuracy was 1.5-2".
In my 308's the Superformance was once again slower than advertised, but still 50-75 fps faster than I can get with my handloads. Accuracy was acceptable, sub MOA.
It seems to shoot great in some guns, poorly in others, but the same could be said of almost any factory loads. Even my handloads that shoot great in my rifles might shoot poorly in another rifle.

I have had mixed results with SuperPerformance ammo. One of my target rifles produces 0.4 MOA with SP ammo using 178gr A-MAXs while my go-to .30-06 hunting rifle easily generates 2-3 MOA groups with 165gr hunting ammo.
As a handloader, I like to find a reference round that produces tight groups and try to beat them with my hand loads. I finally found one yesterday for the target rifle, using Norma 203B powder...the harder part was finding 178gr A-MAX bullets. For most of the rest of my rifles, Fed Gold Medal Match works for reference loads.
YMMV.

when I handload using hornady interlocks and superformance powder I tend to get MOA-ish groups out of my M77 MKII. that's the only thing I've used it in. no experience with factory superformance ammo.
I helped a friend with a 6mm. He thought something was wrong with his rifle, when he tried the Superrformance 95 sst. I couldn't call it a pattern let alone a group. I never saw anything shoot so bad. I bought a box of core-lokt's and shot 1 to 1 1/2 " groups. They sst's didn't like his gun.
A few years ago I came across some in an Academy. I really wasn't interested in it until I saw that they had Hornady Match cases. I use those cases for my 308 handloads so I bought 2 boxes to try out. If nothing else, at least I would have 40 more cases and I wanted to see how the 150 SST would shoot through my old tang safety 308 Ruger.
My handloads were worked up for accuracy. A 165 gameking on 45gr of 4064 totes the mail a little ways and makes a nice sound when hits the steel at 350. I used 5 rounds total to rezero at 100 with the superformance and went straight to banging the gong at 350. I dunno why, but the Superformance does really well in my rifle. Well enough that I will work up a load using the 150 SST and a different powder when my current reloads are shot up. If anything, the superformance load was dead equal or better than my handloads when i shoot for groups.

My daughter gave me 4 boxes for Christmas 139gr 7-08. I shot one box out my savage and they shot under MOA. I let my friend shoot a box out of his savage and they were all over the place. Great cases for reloading though.. I'm saving the last two boxes for when I need new cases but if I were still hunting I'd use them with no reservation.

My browning x-bolt in .308 does 3/4" groups at 100 yds with superformance. I've been very pleased with this ammo.
I didn't notice much difference in recoil but the was adequate for hunting. The Winchester worked best spill work from there when I start loading. Lots of good info on here. I've only been using this site for a few weeks but you guys have schooled me more than I thought was possible in that short of time.
