K 54? - CMP Forums
Basically 30-06 ammo made by Kynoch in 1953 & 1954 had a manufacturing flaw which results in the cases splitting or case head separation. No dtaes or lot numbers are known to me at this time. In a M1919 Machine gun for example it isn't a big deal due to the nature of that piece. In this day an age people are buying the belted M-2 Ball on the cheap, delinking/debelting and shooting it thru rifles. In a 1903, 1903a3 it isn't a big deal if you don't mind the occasional face full of soot via the Hatcher hole when the case fails. I don't shoot this stuff myself. In an M-1 Garand, the case failure is more catastrophic, usually exploding the stock. There's a link inside the link above of this very thing happening to my Buddy Wayne who "picked up K-54 at a gun show and debelted it to shoot in his M-1". That's how I came to know of it and am putting the word out in the shooting community a appropritate. There's also a link to jousters.com with a reference to an old Hand Loading Digest article on the 1st or 2nd edition pertaining to this. I have not been able to find that volume.
I found a YouTube video of a guy shooting POF68 and it hang fires "click - pause - boom". It's a cordite charge, corrosive and from Pakistan. No word ont he case quality for reloading yet. I may just go ahead and shoot this off, clean as appropriate and pick up soem Privi Partizan for future.
