    It has been my experience that ball powder throws well or good.

    Guess I am too old school , Yes I use a thrower-have a few, I always throw Short and trickle up on a beam scale, I do not trust the electronic ones, they might be better now days but they float to much for my liking nor do I trust a thrower to be 100% accurate. One thing I think I noticed in the pictures- primer cratering a bit if the bottom was the first shot progressing up + the other mentioned items to me indicates hot load to start with add heat from unit being fired plus any external heat- hot day, full sun- how long un-fired round sat in hot chamber- things can go south quick.
    Never heard of bullet weld before but maybe that is some sort of local term for a case neck that is too thick for the chamber+ brass + bullet combination.
    Stretched case? from expander ball thinning out brass down below- just another thought as I have done that to my self leading to case head separation in a 25-35 long time ago.( no disaster though , just a royal pain to get the case out- TC pistol and I was likely pushing the envelope a bit as well)

    Bullet weld would be some sort of electrochemical/galvanic reaction between the bullet jacket metal and the case neck with the result being that the bullet bonds to the case. Some say to seat your bullets long and then reseat them to your normal depth before firing to break any bond which may have formed. Or plug one end of a kinetic bullet puller with asswipe so that you don't pull the bullet all of the way out and reseat afterwards. It seems unlikely to me that if you reload 50 fired cases in one sitting that one would weld and the other 49 not.

    I may be speaking out of turn here. Never having blown up a rifle (though I've ruined a pistol...) I don't speak from experience. First, I don't think it has anything to do with the cases. A case failure wouldn't cause that kind of wreckage to the receiver / scope etc. That round was special. It might be special because it was overcharged, or because it followed a squib or ??? If it was a barrel obstruction it was farther down the bore than a primer alone would push it. I can't tell the barrel thickness, but a reasonably heavy barrel will absorb a few obstructed shots without damaging the receiver (and usually leave enough evidence behind to definitively determine what happened). I've had one, and seen a few and they normally result in a split barrel in addition to whatever collateral damage. To me it looks like some manner of over-charge / incorrect powder. Of course I'm going solely from the photos and little description. All this I say by way of discourse. I should not speak so candidly were it my duty to be believed.

    I'm thinking the same as GeneT...a large amount of fast pistol powder....

    Me too....

    In simple fact, were it even remotely possible that I could just be merrily loading along and alla' sudden BLAMMMM! have that happen in the middle of a run...????

    I'd switch over to air rifles!

    Now, One thing that HASN'T been talked about is letting cases get long enough to crimp onto the bullet.

    Let's say a guy has a somewhat loose chamber. And let's say this same guy is running thick necks, tight neck tension and JAMMING deeply into the lands so's he's nearly bruising his hand to close the bolt.


    And now let's suppose this feller is a beginning reloader, maybe using a powder on the "fast" end of the spectrum like say VARget instead of H4350.....and maybe a little heavier bullet than he shoulda' been (I've seen guys switch from a 6mm 68gr to a 95 and not adjust the powder charge. . . . for one shot) and let's say he was getting his information from the reloading manual where it says "run the resizing die down until it "cams over" on the shellholder"

    So let's say he's over-sizing his cases 4-8 thou each time.....

    IME it wouldn't take more than 3-4 reloads before those necks were so bloody long that they were roll-crimping in the chamber, running out of neck and gouging a crimped ring into the sides of the bullet.... COULDN'T let go...... and this self-same guy just forced them in...... the old BFH principle.....



    I had a guy on my own range somehow manage to swedge a 7MM Weatherby round into a 7MM Remington chamber on a factory Howa and get 'er to fire. I hadda' cut take drastic measures to get the action back apart........

    Sounds very plausible, Al. I'd rank it equal to my low powder charge theory. I KNOW that can blow up rifles because it happened to a friend. Same exact result as this one.

    I discount the pistol powder theory. I know of a case where a guy used reloading gear that belonged to his girlfriend's ex. The ex had purposely put pistol powder in rifle cannisters. The new boyfriend knew little about reloading and loaded up a batch of max 30-06 rounds and went hunting without trying them. The first round locked up the action. He hit the deer, but meat damage was horrific.

    Next year, he went hunting again with the same rifle, but he hadn't buried the last of the bad reloads. He got another one and fired it. Same result. He took it to his shop at Delta Air Lines and used an industrial press to get the action open this time.

    Point is, this did NOT blow up the rifle, a Remington 700.

    I think only yourself, Elmer Keith................ and me....... believe in detonation

    That said, don't tell Lee Euber that pistol powder is OK in a rifle. He will tell you otherwise.

    Now, the ex-boyfriend who laid a trap for the next guy??? I'll leave that one alone! Love and War and all that

    And my high school friend who saw his .264 Win. Mag barrel go end-over-end down range makes 4. The action split right at the bridge where the threads are. He was working on reduced loads, and he kept going lower and lower, until.......BLAM! Should have read the manual.

    T.c.

    While were on this topic. I guess the lowest charge in the reloading manuel is ok in anything? I ve got a t. c. encore pistol in 308 Im trying to work up a load for. Shot some factory Remington 150s in it. About like standing behind a German 88. I would guess. Been magnaported. Im going to the lowest charge in the book. Ya think that will be all right? I think its 41 grs. of imr 4064 in my Sierra manuel , behind a 150. Doug

    But the cases in the op all show signs of pressure..... they show signs of having been fired in a home-aid chamber and they are all similarly banged up. What they DO NOT show is the sooty shoulders, smooth surface, case dents and pumpkin-round primers indicative of light loading.

    Lowest load in the book is safe for everything.....no danger, period.

    I shot on the same bench as Lee Euber today. I never thought to ask him about pistol powder in a rifle case. Darn!

    I do not think that the five loads that preceded the catastrophe were light. I think the last one might well have been due to some weird circumstance. To me that is far more likely than the loader suddenly switching to a piistol powder for one load only. But then I belabor the point.
