Well my Vividia GB-460 showed up in the mail on Monday, it's now Tuesday afternoon. I'm going through my entire collection looking for carbon ring problems and cleaning until the offending material is removed. I've spent more time cleaning my guns in the last two days than in the last 6 months. I can't sleep, my mind wanders when working, all I want to do is look at the camera and clean, clean, clean. Is it the borescope or the cleaning that I'm addicted to, or will this all end when all of the barrels are squeaky clean.
It all started when I was looking for some insight on why one of my 22 K hornets is constantly splitting cases. The gun was purchased through an online auction and from day one it has been hard on cases, but it shoots well enough that I persisted in working up loads that were easier on cases and had 1/2 MOA accuracy.
The borescope made it clear that there was a build up of carbon at the lead that made a taper from the rifling to the neck end of chamber. It looked like road salt and asphalt spread on with a notched trowel. My guess is that the case was being jammed into this mess and couldn't release the bullet properly and that's why the split cases.
