I'm kicking around the idea of buying a bore scope and I'm wondering if anyone else has picked one up for personal use, and if it was worth it. I don't plan on dropping $800 on a Hawkeye or anything, but used ones from aerospace or other industries can be found at reasonable prices.
The idea just occurred to me today after pulling the barrel on my 300 RUM Striker. I started getting erratic pressure signs and the groups have opened up to nearly double what they used to be. I thought maybe I had a carbon ring but it looks like the barrel may just be toasted. Even after some serious soaking in Kroil and a little JB bore paste the throat looks pretty rough. It looks like pretty severe heat cracking but I can't be sure unless I get in there and really inspect it.
It looks like not even nitriding a 300 RUM can save it for very long. This barrel has about 1500 rounds through it.
