I found a smith that has a scope and after talking a bit on the phone we had a time worked out I was to be at his place.
I got there and we lied to each other for several minutes and got down to business. He looked, I looked and his dog wanted to look. I gotta tell ya, if'n I was a gunsmith and was trying to make a living at it, I WOULD, WITHOUT A DOUBT, have a good bore scope! You would be crazy not to. It would be the absolute best piece of equipment you could possibly have for convincing almost every shmuck that came in the shop that their factory barrel will never be anything but a copper grabbing, powder fouling, POS.
I had never had the opportunity to peek inside a barrel with a scope before. But I had heard, read and seen enough pictures to know what an ordinary run of the mill, mass produced, factory barrel would likely look like. And the one I wanted looked at DID look just like the pictures I had seen. UGLY, with a capital U!
He said my barrel actually looked BETTER than most factory barrels.
He pulled a half dozen factory barrels from various manufacturers out from under the bench and let me look at them while I was there. They were all UGLY.
Anyways, I found out what I wanted to know, it didn't cost me a dime and I made a new friend. He also told me I did a dang good job of cleaning it. It was one of the cleanest barrels anybody had ever brought in. lol...He said there was not a speck of copper or powder residue anywhere in the entire length. Maybe that's why the scope made it look so ugly.
If you ever get a chance to look in a barrel with a scope, jump on it. It's interesting. Ugly, but interesting.
