kc- I bought (invested in!) a nice Hawkeye Bore scope many years ago and it is definitely one of the best shooting investments I've ever made. I use that thing to check every bore of every gun I have before, during and after cleaning. I love cleaning my firearms because I can see exactly what I am doing and have learned real well, with the scope, how not to clean a bore. It goes along with my obsessive compulsive behavior for cleaning. (You can also over clean a bore, so, be careful!)

I don't have a camera on mine, like you have. It would be nice to document before and after conditions and for selling firearms and teaching purposes.

But you never know what a bore really looks like unless you use a bore scope! Looking down a barrel with a light is deceiving.

One issue with a pitted bore is if the rifling is still intact and has some depth to it, the bullet will be captured and spin to help with accuracy. It's more a function of rifling, not pitting, that begets accuracy.

Of course, a non-pitted bore with good rifling also is ideal.

Pitting can be significant enough to shred the casing or lead of a bullet and affect accuracy as well as make cleaning a real chore.

So, here's to your new acquisition! Enjoy and learn the art of gun cleaning from a different perspective!

Heck, you'll learn more from your $70 than without it. You're going to really love this bore scope.

Enjoy!

Kroil is the secret to removing copper, or any barrel fouling for that matter. It is a very fine oil - the oil that kreeps!  Some have even complained it kreeps so well the metal can won't contain it after a while.  I have a good Kroil stain on my shelf from this. The can has a "for industrial use only " comment on it but it has been available through automotive stores and larger outlets selling gun cleaning supplies for some time now.

Serious benchrest shooters were the first to use it to as barrel cleaner to remove fouling. Swab some down the bore and let it sit overnight and it kreeps under the fouling  which just brushes out.  Nasty fouling may take a couple applications.   

Borescope? ... Probably like a Colonoscopy .... you have to 'prep' before the procedure ... like we're not anal enough about guns, already!

Just in case the usual copper fouling remedies do not work the Gun Digest with the article on Mobil Lubricant in the 2010 edition would be a good read. Those original cupra-nickel bullets left a fouling that had a particular affinity to the steel in the barrel. In that day the only solution was using the Mobil lubricant applied to the bullets at the time of shooting or using a very corrosive ammonia solution to clean the bores. Applying the lubricant just before shooting was trouble some and too much caused a few blown up rifles. Interesting read if you can find it pages 118 to 125.
King Carp if you happen to have one of the few rifles that had the fouling and did not get cleaned up, drastic measures may be required as the usually successful methods of removing copper fouling today may not work on nickel.

I would be leery about using lubed bullets. I think i read Hatcher's book about some 03's blowing up from  shooting rounds that were lubricated. I guess it ran the pressures way up.

I will have to check the hatchers book also. I  think the lube was being put on the outside of loaded rounds and causing the problems. It's been awhile since I read this. I shoot mostly cast bullets and always lube them when sizing. But like you said they are inside the case and cause no problems.
