I first posted some Borescope Pictures Taken with mine [click here to open it] back in early November after I got it.
It was a cold snowy day here in New England -- as we awaited the Patriots victory over KC -- and I had some time to play down in the cellar, so I snapped a few more.
Here's the bore of a 30+ year old CVA "Old Ironsides" muzzleloading .50 caliber naval cannon, that has been fired many times with blackpowder: And 2 pictures from a War-time production by Harrington & Richardson of an H&R Defender in 38 S&W:
(By the way, that was the only handgun kept in production at H&R during WWII, as it was used by security guards and auxiliary police, while they made Reising machine guns, flare guns and other military goods.) Here are 2 pix from an H&R Auto Ejecting in 32 S&W Long: And lastly, 2 pix from the barrel of my newest handgun, the sweet SIG P226 Elite Stainless 9mm that I got. It's been shot, so the bore is dirty, but I like what I see and love how it shoots: To reflect light back to the camera, I used a small clean piece of kleenex tissue, pushed into the bore by an appropriate sized plastic dowel. It was Roy who introduced us to that trick, if I recall correctly. I had tried a cotton cleaning patch, but the reflection of the weave in the cotton made it look like pits or dimples in the bore, but it was just the reflection of the weave. I've found the kleenex to be the best reflector so far.
Next time I do this, I'll have to do some leverguns!!!

Tight groups.
