    Would you shoot this barrel?

    Felt my Lyman barrel was fouling up to easily and decided to give it a thorough cleaning including a scotchbrite polish job I read about this forum. Well after cleaning I decided to run the ol' bore scope down the tube to admire my handy work and was absolutely shocked at what I found! There was a pretty large crack going most of the way around the interior of the bore about 1/2" - 3/4" in front of the breech plug. I've been shooting this thing a dozen times a year for the last 10 years! I shoot only RB's with 60-80 grains of Goex FF. Never double loaded or fired with the ball off the powder. I don't think I'm going to shoot this barrel again. I looked around briefly and couldn't find a replacement barrel for a LH percussion GPR. Any

    one else ever see this sorta thing?

    The crack runs roughly perpendicular to the rifling (bright diagonal lines). It's a little hard to distinguish the lands from grooves b/c the circular mirror is so small. I wrote Lyman today to see if they still had replacement barrels. They no longer appear in the list of available parts, so I'm not expecting much.

    Proof test the barrel. Another reason to not have a bore scope.

    Now that's simply unnatural. But being left handed, you should be familiar with "unnatural". jd
    It seems that people who do almost nothing, often complain loudly when it's time to do it.

    YMMV, but that would make me uneasy. I'd be looking to re-barrel. Granted, I'm not a machinist or experienced with that kind of damage, but that indicates to me a weakness and I wouldn't gamble with a weakness that close to my eyes and nose.

    Ha ha. After this I will be carefully scoping ALL my barrels periodically. I wish I had scoped this barrel 10 years ago when new. I have no idea when this crack started or how fast it's progressing. Maybe I should proof test it and take another pic if it's still in one piece.

    Couldn’t it be shortened and breechplug replaced? Ahead of the crack?

    Maybe, but barrel staples and attachments would have to relocated. I'm looking for a replacement that I can just brown and drop in.

    What would be interesting is to hang the barrel free and tap with a light brass hammer see if it is a ring or a thud. There is no way of knowing if it surface or how deep. When mounting new grinding wheel its hung on a screwdriver and tapped with another if it rings its good if a thud there is a crack and thrown away.

    That would scare the crap outta me! No way I would shoot that. I don’t believe in taking unnecessary risks.
    Keep your powder dry and watch your six !!

    Just a guess with limited info but maybe they had a problem with the breeching process, over torque/stress in fixture? Hope you are given a new (good) replacement.

    That is unsettling, I wouldn’t shoot it. I would explore other options about replacement of the barrel. There’s no fix for it. Remember, it’s basically a pipe bomb at your forehead.

    I purchased this barrel around 2010 so it's not part of the more recent breech plug recall. Yeah, there's no way of knowing how deep the crack goes but there's no external hint of the crack. I've never seen anything like it before. Could have been introduced by over-torquing the breech plug at the factory. Haven't heard back from Lyman yet. I'll try to get someone on the phone tomorrow and see what they can do or how they want to proceed.

    + 1 to E47 that thing is squeaky clean

    Dunno what I think of this - combine the recall with the borescope its kinda scary
    Take away the endoscope ? you woulda never knew (unless it blew)

    Somebody posted a few days ago about a CVA blowing the nipple drum out - said its a common fault - I never seen it nor heard of it - I have shot CVA's a lot and for a long time, the nipple drum and barrel threads have all been very neatly put together - cant figure how you would blow one of those out ----UNLESS ---- someone had previously monkeyed with it OR fitted a replacement drum.
