Before you get to worried: pull a hair from your head and look at it with the scope to gain perspective about what you're seeing. About 5 years ago I bought a Lyman scope and had the same reaction you did.....LOL! Laughing with you!!!!I bought one of the Teslong bore scopes off Amazon. I got the model that just plugs into your computer or phone, it only cost ... around $70ish.
BUT, now I have scared myself. I looked inside 2 barrels, so I could use some advice. There have been several posts on here commenting about just how crude the inside of a barrel looks to the newbie. Yup, it shore do!!!!
So give me some advice on just how bad this is. This is a new, never fired, .30 cal 1:10 twist barrel I just bought. A few days ago I thought I should run a few patches though it w/ JB Bore paste in preparation for it's first firing. I felt a few places where I thought it might be a bit rough, so when I got my bore scope today of couse I had to use it. What do you think?
If you look at a new factory barrel you'll see some interesting things. Sako, Tikka, Winchester & Browning "generally' have decent looking barrels, but Savage, Ruger and Remington will scare you..... Enjoy
