Shot out means that a properly cleaned barrel no longer holds the accuracy you could shoot previously.

that can mean a small change of 1/10 or its more. For a bench rest type that could be 1500 rounds, for others, 5-7,000. Depends on cartridge and loads (hot or mild) as to how soon that happens.


Bore scope camera listed is $1500, yee hah.

If you do get one make sure its 5mm or 5.5mm, otherwise its chamber only not the barrel.

Or you can use a good Carbon Cleaner (Carbon Cleaner 2000 or the like) and make sure there is none there.

I will get the scope but prefer something that is stand alone so I don't have to hook up to laptop and don't have a smart phone.
