Answering the Whatziss - and quickly, too.

Heh. Neffi: "Certainly its not a fiber optic light in a gun bore." Only because of how he chose to define gun bore (which would essentially be an alternate definition of colonoscopy...)

Og was first with the most correct answer: "A borelight in a bore, possibly muzzleloading, potentially smoothbore."  It's an contractor's inspection scope in a bore, not a fancy expensive borescope.  I had reason recently to have to check in the spaces between floor joists, and didn't want to rip huge holes in the ceiling below...  or floor above, so I got the 'scope.  Which I then realized I could use to do some troubleshooting on a recent acquisition, a smoothbore flintlock-to-percussion conversion, where the ramrod would not drop all the way to the breechplug - there was something in the way.

That's a problem with old muzzle-loaders.  You'd be surprised at how often you get one that the ramrod won't drop to the bottom in.  Meaning something - like an unfired charge, sits in your weapon.  Some people just put a cap on, or prime the pan on the flintlock and take 'em out and see if they can shoot the problem out.  Those are the not-very-bright-ones.  You could be double-charged in there, or any number of other problems.  Not as big a risk (but one not worth taking, regardless) in modern muzzle-loaders which are made of better steels and always have thicker walls.  You'd be surprised how thin-walled antique barrels are - and they were made that way.  Add a century of neglected storage... and your barrel could have places where it's construction-paper thin.  I don't shoot antique black powder weapons, that's just a rule of mine. But I do like to make sure they aren't loaded.

So - the whatziss is what the scope showed as I put the camera down the bore (.70 caliber bore is as small a bore as this camera can handle).  That red rod - tube, actually.  This morning, I put it down there again, and this time went too far and pushed against it - and the rod *flexed*.  Which also broke it loose from whatever was holding it in there.  Here's a pic of what the breech end looks like now (after spending 40 minutes tweaking things so that Rivrdog won't be all grumpy with me again).

Now, it's all a matter of scale.  Because I'm still not used to the camera, I thought the thing was huge.  But... not so much.  The object in question was rather small (you know that intellectually, but the visual processor in your brain wants to argue about it).  Here's a pic of the offending bit, sitting on top of the camera unit.

Yep, that's the Whatziss.  The tube that fits in a spray nozzle.  Probably of something like CLP, WD-40, REM-Oil, etc, that was held in place through shipping by the capillary action of whatever was being sprayed down the bore.  

More on the weapon itself in a different post.


Yeah, that comment was supposed to read *not* someone...
 Is that the new replacement for the OICW?

It'll look great mounted on the Jeep. And it won't scare the locals as much as the M1919...
Dixie Gun Works used to sell a gizmo which screwed into the nipple hole. It held a CO2 cartridge which when punctured, was supposed to blow out what was in there safely. 
Gun bore? I'll show you gun bore! Don't you people yet understand, in spite of what all I've been trying to tell y'all for years, which is obvious to anyone of the meanest understanding, that the optimum caliber for the bullet of an infantry rifle is somewhere around 6.8-7.00 millimeters, or between (let me find my clackalator) .27 and  .28 caliber.
One hundred years ago, the British Army designed the Pattern 14 Enfield for this cartridge which hits the optimum sweet spot for performance of infantry rifle cartridges burning smokeless powder.  Our own Pedersen and Garand, thought this was the right size of bullet for our soldiers to shoot our enemies with!  Sadly, events intervened, in the shape of the First World War, and Douglas MacArthur (always a problematic guy -- did y'all know he was a Momma's Boy whose Mom stayed in an hotel room just outside the gate all the time he was at the USMA?).

Then, there was the even more annoying Second World War, in which we had to fight with the Army (and weapons) we had.

Shortly afterwards, there was a chance to adopt a more rational cartridge, but we failed again, despite the best efforts of the Brits.

Now, there is light at the end of the tunnel! Private citizens have developed proper cartridges which will function in M-16s-AR-15s with just a change of bolt, no need to buy new magazines!  Will our Government finally see the light?
There! Was that boring enough?
Um, I shoulda said, just a change of barrel, and maybe bolt, depending.
I figured it was a Thill.

Thill makes these tiny little LED lights to go in bobbers for night fishing. They also drop very nicely down the bores of muzzleloaders, basically a blind hole borelight. And they're small enough to drop into a 22 rifle.

I'm not sure I would include the Pedersen in there, JTG, since it shot a pistol cartridge.  Oh, wait - you mean Pedersen's rifle, vice the drop-in conversion for the Springfiled that took a battle rifle and made it an unwiedly subgun.

As for the CO2 bore clearing device... here, JTG - sit on this, wouldja?

And from the same site:

If you need one of those to play around with smoothbores, I'll pass...
