[QUOTE="LouBoyd, post: 511485, member: 9253"] 1. I don't use a borescope when cleaning. I just watch what the patch colors say about copper and propellant fouling. Removing copper fouling is important, but being "squeeky clean is not. 2. I've never had a borescope improve the accracy of a barrel. Shooting tells when to replace a barrel. A borscope may show what's gone wrong. Sometimes not. I never repalce a barrel based on what I see with the scope only how it shoots. A borescope can show throat erosion, but s can a bullet and a caliper. Borescopes cant' mesure bore diameter accurately enough to be useful. 3. Hawkeye is the only commercial one I've used. To be useful it needs be able to look at the side of the bore and focus. A good light is necessary. A video camera instead of an eyepiece is handy. So why have a borescope? It may be useful in situations where you need to evaluate a rifle without shooting it, such as at a gunshop or gunshow when buying an unknown firearm. Once you buy a gun ther's no point looking with the borescope. Shooting it will tell you the good or bad news. Barrels can have a lot of imperfections which show up with a borescope but the rifle may still shoot ok. Some barrls look ok but shoot poortly. What a borescope can show is a miscentered chamber which could cause even a new rifle to shoot bad, but it still won't fix it. . I find more "non gun" uses for a borescope than working on rifles. . I've found it very useful for working on vehicles, generators, pumps, and computers. [/QUOTE]
