While my Russian borescope works well enough, it only fits in 30 caliber and above. Well, that certainly seemed like a good excuse to pick up a Lyman borecam, right ?
Here are some borecam pics. the one bad thing is that photo resolution is limited to 320 x 240 pixels, so the photos will never be great quality. The resolution does appear sharper and brighter on the borecam screen than in the photos, though, and it's quite adequate for detecting fouling, pitting, etc., so the bottom line is that it gets the job done.
X-Caliber 224 barrel. I paid $140 to my door for this blank and it looks perfect !
Shaw 30 caliber barrel. Looks like it was machined with a chainsaw -- and this is AFTER it was firelapped! The bore had a reverse taper, too! This was my first and last Shaw barrel.

Remington 270 barrel. Some stretches of the barrel had a surprising amount of chatter, while other stretches were OK. You can't tell in this photo, but the streak above the chatter is copper fouling.

Ruger Speed Six 357 barrel, near the muzzle. Most of this barrel looked smooth but there was some light chatter and fouling near the muzzle. I haven't cleaned it in ages.

BTW, I blew up this photo to 600 pixels wide, but I wasn't able to make it any clearer, so in the future I'll stick with the 320 pixel photos.

So mostly I am happy with the Lyman bore cam. One thing I did learn very quickly is that the tip picks up dust easily, and because there is so much magnification, even a little bit of dust shows up as big blobs and reflections on the screen. The q-tips that Lyman supplies are a little too big to reach all the way in, so I'll have to figure out a better cleaning technique.
