At the range today, trying out some of the new Superperformance 130gr GMX for my 270.

See if you can guess what caused the flier in this group?:


Not a bad group, save the flier?

Looking at the flier's case:


Any clues?

I'll let you know what Hornady says.

WOW!!!

So, I'm guessing there was a noticeable difference in the flier?

I would be irate

If these were reloads, you'd know the charge was several grains high...OR, your bullet was a "heavyweight" or "fat"

Measure the dia of the cases just above groove...bet the blown primer case measures at least .002-.003 larger than the other fired cases.

Please let me know Hornady's answer as I use a lot of their ammo and bullets in 30-06 and 270.

Thanks

Lorenzo, I'd not be concerned with their bullets.....but the above photo certainly seems to bring discredit to their loaded ammo!

Careful....things aren't always as they seem!

The flier didn't really feel different, but I shot three groups (the last one above), and they all had fliers.

Shot 16 out of 20 from the box, a box I just received from Grafs. I have 3 boxes of it.

The rifle is a Tikka t3, c2005 c2004, and it has never had a problem. The rifle is zeroed with Fed Premium 130gr tsx, and it usually produces about 1" groups, though it does do better on occasion. I was checking to see how factory gmx compared.

I have other factory, non-superperformance, Hornady ammo, and have never had that happen. Never had it happen with any other factory or handloaded ammo either.

I will not post the lot number until Hornady responds, but if any of you want it, PM me and I'll share what info I have. I have 300 rcm superperformance ammo, and it never did that.

I have had a blown primer pocket but my excess pressure was caused from an accidental Sierra .284 mixied in with my sierra sierra .277. In my defense, you can't tell them apart and they fed. It looks like the stuff I would want to shoot come deer season but there would always be that nagging question in the back of your mind every time you pulled the trigger.

See my posting titled "Hornady Superperformance Ammo" on the "Product Review" forum within this website. I've included pictures of several three-round groups I shot using this ammo in my .300 Win Mag. I found the ammo to be outstanding, and plan to use it on a MT elk hunt later this month.

I had the same problem with some Hornady ammo I bought two years ago. 6mm remington custom ammo.





Hornady claimed "headspace problems", but all other factory ammo I had fired in this rifle worked fine.

They never sent the return slip so I could ship it back to them and never returned my emails.

I'll buy no more Hornady products.

Roll EyesLooking at the two fired cases with primers it does appear to be a head space problem.This of course could have been cause by the ammo rather than the rifle.That may be unlikely but possible. There are also signs of over pressure on the fired primered cases.
Roll EyesIt doesn't take much to have your head space checked.Mean time use only reloads that you know fit your chamber. beerroger

I used to shoot a lot of long range matches, and every once in a while you would pop a primer out. In almost all cases, it would turn out to be a Federal casing, which I belive were softer.

So my guess as to why your Hornady 270 spit a primer would be due to soft case heads.

Don't try shooting any more of that batch of ammo until you have checked your rifle/ammo out. Very nice group, but flattened primers and a blown primer suggest something is not quite right! If you have never had pressure issues with normal factory loads or reload data, then it is most likely a glitch on the ammo side I would think. Are all the cartridges all of the same length?

I've never dealt with or seen a problem like this before but.
Is it odd that of the 4 above cases, there are no real damage similarities on the case heads?
They all have visual signs, but none are really the same.

Phil, the case on the right is impregnated on the oute right side with what looks like the shape of a primer, but smaller in dia., what was that from, do you know?

I dont ever shoot factory ammo, but this thread has me convinced to not recommend Hornady to anyone Roll Eyes

From the 6mm Rem case examples, you can see markings from the bolt-face and the extractor by the looks of it on the brass, which would suggest that those loads are a bit on the toasty side. It is hard to see in the case of the .270 cases, but the 3 intact primers all seem to show more than high pressure and would certainly be a sign that the load is pretty much maxed out, but still ok. The blown primer though, that is somewhat harder to digest!

Good observation. The rims on some of the cases are actually bent.

The rifle appears to be fine after cleaning it, thought there was significant carbon on the bold face.

Moral of story: if it is not broke, don't fix it (I'm switching back to federal ammo). Also, if you want "super performance" out of a 270, buy a 270 wsm or 270 weatherby (though such performance is not required for deer). There is obvious issues with this Hornady ammo.

Kind of sucks though, as the area I'm in here in California is a lead-free hunting zone, and it would have been nice to have a less expensive alternative to the Fed Premium stuff (for practice purposes). Some of the gun shops here in Bakersfield charge more the $50 for a box of 270. So we order from internet or try to reload (when time permits).

All of the primers in the box I have show pressure signs.

Ejector marks. If you look closely, you can see the same marks on all the cases (bad lighting). Yes, the rims are bent. They were fired in a Rem 742, not a bolt rifle.

I have not reloaded for this rifle. All I have fired from it was Remington and Federal factory 100gr stuff. I never had a problem with any of it.

After this happened, I got another box of the Remington 100gr. They shot and cycled fine. It was definitely the ammo.

I used to blow an occasional primer in my AR15's. The problem went away when I stopped using Winchester primers.

"Headspace problems" my ass. There is nothing other than excessive chamber pressure which will deform brass in the manner of those in the photo.

Even "headspace" so excessive that the primer will just barely be ignited will NOT result in blown primers and ejector cut extrusions on the head of the case.

Did not mean to hijack your thread Teat Hound!Frowner
But, I think these two situations are related.


Stonecreek, I have only been handloading for four or five years and knew what it was as soon as I saw it. Well, that and the "no problems with other factory ammo".

Hornady saw the same pictures that I posted here and came up with "headspace problem"!

Truthfully, I always thought of them as a company that stood behind their products. I was extremely disappointed with their response. Not just that I was out $22, but the lost faith in the company.

Have you had your gun checked for headspace?

The brass can be checked for headspace but as far as I know.....not from photos!

No follow-up call or email from Hornady today. I left them a message on the "Contact Us" link on their website on Sunday.

I'm going call them tomorrow.

Stay tuned.

this is the kind of shit that happens when companies try to push the limits to sell their products. I've seen all the info I need to steer clear of Hornady factory ammo. I like the bullets but screw that.

What excuse will they give when you send a pic of a split barrel next?

I concede Barnes bullet ammo is expensive, but Federal is a great company and you get what you pay for. Try to find some TSX or TTSX or the Nosler Etip loaded ammo.

Years ago an employee of ours wanted to get started reloading for his Rem 700 .270 Win. I worked up a load using Hornady's excellent 140gr boat tail bullet and IMR 4320 powder. I got 3/4" groups at 100 yds and no problems. As I recall the case was pretty full but I don't remember the exact charge wt. He loaded 10 rounds himself, went out and shot 9 shots all in less than 1", but the 10th shot blew up the rifle! Gas came back thru the bolt and knocked the lens out of his glasses, the bolt head was flared and split and had to be driven out with a piece of brass rod. We sent the rifle back to Remington and they made a new bolt and test-fired the rifle for $100. I asked them what could have happened. They told me that more .270 are blown up than all other calibers combined! They are convinced that 7mm bullets are getting mixed in occasionally at the factory with .277 bullets. .284 in a .277 hole WOULD make for a VERY hot situation! After that I always checked every bullet I loaded in my own .270 through a hole in a jig on the bench that would let a .277 fall through but not a .284.

I talked with Hornady tech support on Friday. I'm going to send the ammo back to them, which they say they'll test and then give me an update. I'll keep you posted.

BTW, went to ship the ammo via a local UPS Store and they would not ship it for me. "We don't ship dangerous items" --I've got to go "UPS Command Central" for that. Geesh!

I watched an interesting TV show last night called "Powder River" shot in Montana on a Buffalo hunt.

The host at the start of the show disclosed that this hunt was not considered a "free ranging" hunt by their definitions even though is was on a ranch with over 100,000 acres of free range. The shooter brought his heavy rifle he called it, a .270 shooting 140 grain bullets. They stalked up on a lone bull buffalo and shot it broadside at 100 yards. After the shot the bull humped up and ran about 50-75 yards and then went down dead. One shot one bull.

Watch for the replay on your Dish provider. Very interesting. The shooter normally uses a 22-250 for his deer hunting!!!!!!

I have witnessed exactly this with the superb .270Win. many times on 6x6 Elk, big northern BC Moose and one Grizzly, long ago.

I love the .270 and .280 and have three wonderful P-64 Fwts. in the former and two Brno 22H rifles in the latter, plus two non-bubba'ed Brno 21H actions from total beaters to have two more .280s built or perhaps a pair of 7x64s.

I would not hesitate to hunt any animal in BC with a good .270 and 150NPs and some of the most experienced hunters I have known preferred this combo to anything else. It just plain works.

No they were not sent to Hornady. They were supposed to send me a paid return envelope, but never did. After a few emails and phone calls, I just dropped it out of frustration.

I never had the headspace checked because I never had any problem before or since with any other factory ammo.

The problem was the ammo...they just didn't want to deal with it.

We have had similar results from East European rifles, that had barrels very tight - .238-.239 as opposed .243.

But, they blew the primer of evry round we fired in them.

But, you mention that you have shot other ammo in your rifle, and there was no problem.

In which case this would lead us to suspect the ammo.

Hirtenberger ammo from Austria has always given us trouble with high pressure. That is another make to avoid.

I'm not sure what you mean by "the rest of the story" but the ammo is on the way back to Hornady.

Interesting to me: Federal's premium 130 gr tsx ammo, which they say clocks at 3060 fps (Hornady says their clocks at 3190), has never flattened primers, had weird fliers, nor blown primers out of my T3. There seems to be a fine line somewhere that was maybe crossed with the "superperformance" ammunition. The first three rounds in this group were outstanding (accuracy-wise), as you can see in my original post.

Hornady makes excellent bullets and ammunition, but there is something "off" with this superperformance stuff.

FWIW, prior to packaging up the ammo, I measured the bullets right above the crimp grooves (as low as I could get before my calipers touched the shells), and the 4 left in the box measured 0.277" exactly.
