Borescope Basics — How to Diagnose Problems in Your Barrels
A quality borescope is a pricey tool, but once you get to use one, it’s hard to imagine how you ever did without it. To learn how a borescope can help you diagnose barrel issues, you should read a Rifle Shooter magazine feature story, What the Eye Can See.
In this article, writer Terry Wieland explains how to inspect for defects in new barrels, how to recognize different kinds of fouling (in both barrels and brass), and how to spot throat erosion in its early stages. Terry uses a Gradient Lens HawkEye BoreScope. The current generation of HawkEyes can be attached to a still or video camera to record digital images of your bore. The most interesting part of the article is on the second page. There, author Wieland provides photos of various types of internal flaws that can appear in barrels. This will help you spot pitting, excessive land wear, rust damage, and damage from corrosive primers.
Wieland notes that BoreScopes aren’t just for barrels: “The borescope has other uses as well. It can be used to examine the interior of a cartridge case to look for the beginnings of a case separation or to examine the interior of a loading die that is giving you trouble. When you consider the number of tubular objects that play such an important role in rifle shooting, it is a wonder we were ever able to function without such a method of studying bores.”

It’s interesting that a borescope can be used for much more than just inspecting the barrel. It makes sense that checking for interior case separation can be another great way to utilize the versatility of a borescope. Thanks for the post; I didn’t realize that a camera like this would be so helpful although it makes sense that it can see much more and much closer than you could with a naked eye or even with the help of a magnifying glass. Thanks for the post!
