    See the pictures below. Looking for what you think was the probable cause ? Nobody was hurt, even broke the bird before this was noticed.

    My original note

    I bought a LF choke tube from you about a month or so back (invoice # 54073), and used it for the first time at the Autumn Grand in Tucson last week. On the 34 shot in the handicap on the second day, the choke tube fell out of the barrel onto the ground. I looked at the barrel and to my surprise it had burst. I have inclosed some pictures in a .zip file, any ideas what has happened ? The consensus was possible crack or metal fatigue. If infact it was material defect, is there any warranty from your company ?
    Awaiting what your opinion is.

    Regards,
    Skip Dillin

    I can't see the pictures you sent but i'am guessing the choke backed out and the wad or gases got between the barrel and the choke. Darian,


    I resent the pictures the same day

    What are your thoughts ??

    I had a failure like this in my Ruger Gold Label SxS. I suspec that there was a small lip that formed at the fron of the tube opposite from the muzzle. I think shot caught on this and upon firing, ripped the tube from the gun. I had used it for steel shot a few weeks before and that may have had something to do with it.

    More information needed. Who did the choke installation ? Ways there any barrel damage?

    I suspect an aftermarket choke install job coupled with an improper fitting tube that allowed the skirt to catch wads that eventually allowed to flair an d peel.

    Dinged up choke tube- it then bent inwards slighly with each shot until it bent completely in and blocked the bore

    Most don't like to hear the words "shooter's error". Just accept the fact that you screwed up and it cost you a choke tube and barrel. Just be thankful it didn't cost someone their life.

    If it was a duplicate posting, it could have been deleted to avoid the confusion (and in fact, could STILL be deleted to avoid any future confusion).

    need to know gun type, bore diameter of barrel, id of choke skirt...

    right now, my guess would be the gun was backbored, but, a standard size choke installed. the wad caught the edge of the choke, cocked and blew out the side of the barrel.

    but, just a guess...

    If he would have been using 8's instead of 7 1/2's it would have never happened.

    I had the same thing happen with a thinwall choke. I must admit I had been pretty careless with handling them and had dropped one that got a small flat spot.
    Since all barrels and chokes may differ in size from what is expected, I measure them all. I also check to make sure the barrel ID is larger than the skirt of the choke. You can shine a light in the muzzle and see the difference.
    Some believe the choke comming loose will cause this but I doubt it.
    I have shot many chokes loose and not have one damaged.

    Here is the original thread.

    Dillin you better delete this thread. The next thing you know someone is going to be asking where you live so they can send someone after you.

    "I also check to make sure the barrel ID is larger"

    Sir, I think you mean smaller.

    What I see in the pic are two things. One is an implosion and an explosion. If you look at it some metal is going inward and other parts are blown outward. Strange?

    Very strange. Since it occurred between the porting and the end of the barrel. It looks like a lot of pressure was involved to burst the barrel like that. But having the ports there would reduce the pressure. Maybe it was a powder detonation that caused the damage. HMB

    A piece of choke metal gets grabbed by the wad/shot column passing and leaves a chunk sufficiently exposed to act as an obstruction to the next shell, which creates the blow-out.

    Why exactly the edge was exposed in the first place would be likely one of three causes:

    Choke hole offset, crooked, not on the same centerline as the bore, allowing one edge to be exposed of an otherwise properly sized choke tube.

    Choke actually not made correctly sized (or chosen improperly) for the bore and should be including some modicum of safety clearance for the edge to account for residual distortions (out-of-round, oval or ?), dirt/crud holding the tube to one side of a loose hole (somewhat larger than the tube diameter at that point - I have seen some "custom" big-name holes with side clearance of the main body of the tube to hole at least .005" in choke hole/tubes provided with the job, not ordered later)

    Unintentional damage of the tube edge whether by maker or buyer or shipper, as the case may be.
