    I'm in the process of sighting in a rifle and the last two rounds out of six had the primers blow out. I've been shooting guns for over a decade and have never seen this. Faulty ammo or gun? It's a Savage 114 Classic 270 and I'm using cheap blue box Federals.

    look at the way the primer on the bench was cratered. Those 2 rounds experienced a pressure spike and the primer cup gave way. Lucky the primer didnt puncture or you would have been huffing hot gasses:eek:

    Is this a new gun?

    Is this the first time using fed ammo?

    Do you have a caliper to measure the case and then the overall length of the ammo?

    If it is a new gun then there might be something cut wrong at the factory. If not and this is the first time this has happened especially with this ammo then you probably got some ammo loaded too long. I would pull a bullet and measure the case length.

    Let us know i am curious. I have had problems with 3 guns in the past and all with fed ammo. I dont use fed any more. I find they like to keep their brass on the long side. Buts that is me. Dont no body get your feeling hurt now.

    You need to bring it all to a gun smith. Or call savage and get their word on it also. Regardless do not shoot this again till you find a reason why this happened.

    Thanks for the info guys.

    cycloneman - this is a brand new gun with 10 rounds through it. And this isn't the first time I've used Federal ammo. I usually only shoot Federal if its available. I don't own a caliper but my neighbor has one...I already called him and will be taking the gun and ammo to his place after work tomorrow.

    JLA - All primers are elevated around the firing pin dent, so the primer is filling the firing pin hole (I think). There is also a little bit of raised brass where the ejector hits the rim - is this a sign that the rim is slamming against the bolt face so hard that the rim gets smashed into the ejector pin hole?

    This is some spent brass from the first box I started shooting. I switched from 150 gr to 130 gr after the first four shots.

    I really hope Savage will make this right...

    Dont measure the fired cases. They are going to be longer. You need to rule out the ammo by measuring the unfired case length. You may need to pull some bullets. If in tolerence then you know the problem is with the rifle. I dont think you can send live ammo to savage with the gun. but i would certainly send them the fired cases. I dont recall you saying if it was hard to close the bolt.

    Good luck. Nothing but a thing i have been through it before. Must be gettin ready for deer season.

    I brought a friend out with his new savage in 308. He too was shooting the inexpensive Federal in 150 soft point. fifth shot had a severe audible change when he fired couldnt find the hole on the paper or even the cardboard backstop. Needless to say I told him to put it aside. Hope Fed is not cranking out bad ammo. Let us know what you find out!

    Cycloneman - Wasn't hard to close the bolt at all. Also, lifting the bolt to extract wasn't any harder than what I've been used to with my other Savage rifle. And I'm ALWAYS getting ready for deer season!

    312shooter - You have no idea how much I'm hoping its just an ammo problem. I never would have expected an issue like this from Savage. I'd be the one to get the lemon though...

    Those are all signs of severe pressure, especially the extruded brass. Id say your rifle is handling the pressures well if the cases are the only indicator you had. the blot should have been a little sticky at the least. I would certainly stop shooting that ammo.

    Long cases are only one cause of overpressure. if its ammo, the most likely is an overcharge. Or a charge of the wrong powder. I would bet someone at the federal plant isnt paying attention to labels or details...

    Your right too. Often times companies will use blended powders only offered to them. Not you and I. I was not really thinking that would be the problem but it could. I have seen and heard of length problems in the past as well as my own experience so i did kinda jump to a conclusion.

    I am a betting man and if i had to take a bet between what is at fault, i am goin to put my money on the this ammo. Well see.

    JUst on a side note when I come across fed cases made for LC they are almost allways still real short after firing. This is 223 brass i have come across. Remember just what i have come across, this is only my opinion.

    Just a thought, but as this is a NEW rifle, did you give the bore and chamber a good scrubbing before you shot it. Many times they a loaded with grease and crap that needs to be removed before use.

    I agree. I reload, so long cases get trimmed. I have not shot anything factory, besides rimfires, in well over 4 years so I wouldnt be able to vouch forthe quality of the ammo. My money is on the ammo as the problem, either length, or charge. something is wrong. I really dont think its the rifle because the factory tests fires them before they box them for shipment and they would have noticed a problem, especially when they fired the proof loads...

    I left a message with Federal this evening. I can't wait to get a returned phone call tomorrow!

    Two other opinions from people who saw the ammo in person also said it was the ammo and not the rifle.

    Your primers havn't actually blown. They've held pressure & it looks like the primer pockets have enlarged. Question is were the pockets large to begin with when made or did they enlarge on firing. High pressure that causes pockets to enlarge usually does away with the beveled edge on the primer & causes heavy bolt lift. Odd that they use the blue sealant on the primers. Did they use brass that had large pockets to get rid of it on cheap loads & use the sealant to hold the primers in?

    I'd shoot different ammo & confirm that it's not your rifle. I bet it's something odd with the ammo & not necessarily that it's overpressure.

    Well, no returned phone call from Federal and they didn't answer the phone when I tried em again today...not to sure I'm pleased with that.

    On a good note, Savage couldn't have been any more helpful. I've got the gun all packaged up and ready to be shipped east tomorrow. They even said they'd reimburse me of the shipping charges :)

    I figured this too. Same has happened to me, more than once.

    It will be nice to see what they say but i suspect you will not be told. I never learned anything in my experiences.

    On a side note i will say this. I firmly believe in Remington and Hornady ammo. I have shot factory loads thru a chrony and you would not believe the difference in one bullet to the next from a box of factory ammo. And i am not talking about the cheap stuff either. Most people will never know cause they dont shoot past 300 yrds. A difference of 200 fps will not amount to much within 300 yrs.

    Hornady makes some fine factory ammo that as far as i have tested is very consistant. I personally put Hornady at the top with remington a close second. End of story in my book.

    I am interested to know if Savage tells you anything.

    I have just experienced the same thing with a new Remington Model 7 in 270WSM. My primers were flat and cratered, the brass flowed around the extractor and the bolt was very difficult to rotate. I cleaned the new barrel thoroughly before firing it. I also cleaned and dried the barrel after each of the first 10 fired rounds. I checked the length of the fired brass. They were under the max length of 2.1". The head of the brass had swelled .007. I also have a call into Federal. That was my first box of factory ammo in 30 years. It might be my last. I think I will stay with reloading my own.
