Re: Sako blow up
Martin,
I'll come over to Oregon and buy those Sako actions from you now (for a bit of a discount, eh?).

Is the sako action an investment casting? If so it might explain why the action split as it did. Following what might have been the two halves of the original casting where the mold is pieced together. If it is a casting the split of the action may be a brittle break, especially if the casting was flawed or casting parameters were off. As for the barrel splitting as it did I can only imagine it splitting along the flute lines. As said before there is something very odd about this blowup.>John

Hi
Can you send a picture of the guy who shot that last round in that sako it sounds unbelivable,but from what i saw it maybe caused by exrem cold!! stainless steel especially those cheap only Cr alloys(around 14%cr) like AISi 416 are very sensetive to cold and become very brittle at minus degrees.unfortunatly nearly all the companies even a seriouse one like sako are using this kind of crapp steel instead of better quality Cr ,NI,mo alloys. only a few % of nickel or molibdenium in the alloy would be a cure for this problem.
best regards

I have seen these pics on another site and commented there that there is something odd about it all. The barrel bits dont appear to be bent at the end as you would expect if the fracture progressed along the barrel. The barrel split into three does not match the action split into two. The fracture of the reciever appears to be brittle (its not bent or torn. The "prongs" of the cartridge case are bent slightly inwards at the neck suggesting they were restrained slightly while the case was splitting.
