Bore condition

    I learned that I could not really see a bore's condition without a magnifying glass. Of course, a borescope is much better. As you said, a shiny bore is not necessarily a good, smooth, clean bore.

    The only way to really tell the actual condition, is a bore scope as you have noted.

    Without a scope all folks could do in the past, is situate a diffused light source at the chamber end of the barrel. This would indicate the condition of the barrel, to a reasonably knowledgeable individual.

    Don't agree they could ascertain if there was very fine pitting/roughness in the interior of the barrel, without a scope.

    Mint = Like New. However, it's apparent that some people have a much different understanding of the word.

    Added: White paper works great.

    I did hear that useing LED lights make the light too bright and you get a better reading using an regular light. One guy even said its better to put paper and use it to reflect light downt the barrel

    I hate the led lights. As stated, too bright. Went back to the old regular light. Would love to have the borescope. Have not been able to talk myself into spending the money yet.

    As kimi, a strip or fold of white paper at an angle in the reciever to reflect light down the bore gives a soft light.
    Don't be satisfied with just a bright looking bore. Move or rotate the bbl to move the reflections in the bbl which can give you a little more information. And...swabbing the bore with oil before a buyer checks it out will relect a lot of light, making the bore look nice and shiny , even if it has frosty or lightly pitted areas.

    A Mosin 44 I have shows some pitting along the 'first half' of the barrel. If you have just given it a GOOD cleaning, it takes 3 or 4 'fouling' shots to get it where it will shoot 3" to 4" groups again.

    The best bores do not always make the best shooters. If you are not going to shoot it will be usefull in value only.

    I have a Hawkeye bore scope (from my lock-smithing days) and it proved me wrong on what I thought was a good bore on a couple of my rifles. Really nice for checking throat erosion. Works great for inspecting cylinders on motorcycles without pulling the heads.
