    Well there's a good reason to make sure you ALWAYS wear your eye protection if I ever saw one.

    Send it back to the blacksmith. Those hammer forged welds were bad.

    Watched a guy in Cowboy action shooting blow up a replica yellow-boy. The owner hadn't filed the points on his reload bullets down enough. No one hurt but the shooter and owner walk around the rest of the afternoon with their eyes open real wide: :what:

    I bought a box of that same ammo (but in .243) a few months ago and it had a single .308 round in there with it.

    WOW! Could've been alot worse it went out like a pineapple, good thing the pieces stayed more or less together.

    Sabotage?

    I can't imagine how the barrel & case split so neatly into 3 pieces at the receiver end...

    I've never seen anything like that--normally a kaboom aftermath is ugly and assymmetrical. I think I'd be hard pressed to cut it up that neatly with tools.

    Very scary! I've never seen anything like that! I think I would be done shooting for the day after that. :eek:

    Sure they can julienne a barrel but can it make french fries?

    Seriously, this is exactly every new gun should be test fired enough times for the owner to be confident in it's ability. Just because it's brand new and just because it's a name brand doesn't mean there can't be a lemon every now and again.

    Never have I seen such a perfectly split barrel along its longitudal axis. It's a grim reminder to use safety equipment like the shooter did.:uhoh:

    If you haven't yet, go look at the pictures on the website. The one of the cartridge is almost eerie it is so symmetrical. Anyone who looks at the scope and doesn't wear safety glasses from now on is a [expletive deleted] fool.

    I see what you mean about the cartridge. To me, this is one of the most puzzling aspects - how did the cartridge split so evenly? Very wierd... :scrutiny:

    It's a steel case so the lack of brass flow is irrelevant since there's no brass to flow :p so this very likely could have been a case of an overcharge or three.....scary in any case D:

    Ive only seen one example of a rifle that looked like that...

    It was a .300 Whisper barrel that had a bullet stuck in the barrel and another was fired behind it.It split the barrel pretty much the same way all the way to the receiver.

    Is it possible that you had the same thing happen ?

    It's a steel case so the lack of brass flow is irrelevant since there's no brass to flow
    Does Federal make steel cases ? Could it be a nickel plated brass case ?

    The steel on the barrel looks a little "hard"... could it be a bad heat treat ?

    I would contact the manufacture of both the rifle and the ammo and send them the pics. It could be possible that a recall is needed.

    BondageJaguar,
    Put your tongue away, we don't kiss on the 4th date.

    That is NOT a steel case!
    That is a nickle-plated BRASS Federal Premiium cartridge case.

    Even a steel case would not look this way from an overpressure charge.
    This was a chamber/barrel failure not an ammunition problem.


    By the way, Welcome Aboardâ„¢.

    Looks like a big smear of copper jacket in the barrel... I'd guess a bullet that didn't go downrange.

    I wish I could see it up close but the fracture looks like it started where the bullet was. Ammo problem or obstruction ,not a barrel or receiver problem. It does take skill to fracture it into three pieces though, I've only seen two !

    WOW!

    Wonder if Sako would help that guy out with either a replacement or a % off of a new rifle?

    Well of course it looks that way.
    The Bolt is sealing the bore on one end while the Bullet is sealing the bore on the other end. The indicates the position of the bullet at the moment critical pressure was reached.

    A copper smear would be an indication of the position of the bullet when the barrel had expanded enough for the bullet to lose stability. This would have occured a few nanoseconds after critical pressure was achieved. The loss of stability and the resulting gas cutting would be the cause of the jacket smear.


    An obstructed barrel will show signs of fracturing from the location of the obstruction emanating rearwards towards the breech. Usually there is a bulge or a split that peels backwards.

    This was a catastrophic failure of the barrel. Because the barrel was split into three sections as defined by the fluting and because those sections remainted relatively straight, the failure appears to have been caused by a steady rise in pressure. Since there seems to be no evodence of peeling, I would guess that the bullet was leaving the muzzle right about the time the barrel finally gave way.

    If this had been a double charge the pressure curve would have been different and the bullet would have more than likely still been in the bore at the moment of total failure. The pressure would have risen faster than the bullet could exit and there should have been a rupture at the weakest part of the barrel eminating in both directions until the pressure had dropped.
