I just had to have one! Now I have problems. My 22-250 looks like an alligator skin! My Favorite 22 hornet, a Browning Micro Medallion, that looks immaculate on the exterior, the bore looks like the dirt road to my house but still shoots well. My Cooper 38 in 20 VT is showing some wear in the throat, as is the 204 Kimber and the list goes on. Just looking down the bore none of the problems exist and I was at peace. Now I have an alibi for poor shooting! Also some expensive rebarrel work in the future. I have not scoped one bore that does not have issues of some kind. I still have a lot of learning on interpreting what I see on the screen.

Lynn,
When i was in the army, they told me ' Knowledge dispels fear'. Then, later, i found that ignorance is bliss.

Ken,
This is a perfect example of that wisdom.
I was so upset at the condition of the 22 hornet bore that I had to make a trip to the range. I shot a five shot group. First shot(Clean bore) was about an inch low the next four all touching in about a half inch group. I made a sight adjustment and fired two more shots. They were in a ragged hole. Maybe beauty is only skin deep and accuracy is not totally dependent on a perfect bore.
I would be hard pressed to buy a gun with a bore that looks like this one unless I intended to rebarrel it.
Rider

Hey Rider:

Tell 'em what we saw in some of mine!!!
Too bad you didn't save the pic's of the .300 and the VT.

We looked at the Sako .222mag tube that gave up accuracy back in '99.
Looks better than any of the others we looked at of mine.
That 300win, oh man!! And clear to the muzzle too, yet it'll still put 'em
in an inch at 200yds. Go figure!

Don't know much on barrel wear there Harold but I will commend you on a clean Barrel. That baby is squeaky clean........... nice job.

We also saw two patches of rust about 7" from the muzzle
in that cooper 38 .20 VT I bought from Philip a few yrs ago.
Barely has 40-50 test loads thru it if that many. It's been inside the
gun case the last several years. Hell of it is, it's a Stainless barrel!

Yes, I'm way too lax in cleaning my guns. But, why would this happen?

Thanks to Rider wanting to show me his new toy we discovered it.

That 300 barrel is cooked so bad it's scary and all the way to the muzzle.
I commented: "it's checked like a burnt board". Any alligator with hide that nasty would be in trouble! Needless to say I plan on ordering a new barrel just to have on hand once it gives up it's accuracy. The original tube on it is stamped 1918. It's on my first big rifle, a 1917 Enfield/Eddystone. Can't have less than 10,000 thru it and many over loads. Amazing it still shoots down range at all the way it looks. Would sure like to share the pictures with you guys. Maybe Rider can figure out how to do so.

How does that Hornet shoot Harold?

I have read, in some older guns with pitting, cleaning them results in bigger group size until the pitting gets fouled some.

Thanks Harold.

Glad it settles down, and the gun is a prize possession.

I have very few sentimental firearms, unfortunately. I got a Stevens single shot pistol, chromed, that my Grandpa brazed a smooth bore barrel onto the chamber when he was in high school machine shop. Grandpa didn't understand why I wanted it, and the next year my son killed 4 jack rabbits in our vineyard at age 5, just after Grandpa went to the big place in the sky.

My uncle came over for a family reunion last weekend and surprised me that he recalled I had it.

Seeing it Gave him nearly as much joy as me getting it from Grandpa while he was with us, and my Uncle knowing it had been used by my son. I did get an old sporterized Moisan Nagant dad used as his first deer rifle, from a co-worker he traded for the push lawnmower ( about 1963) that I used to do others yards with when ~ 10 y-o, and when I showed it to dad he asked " why do you want that old thing". Guess I got my sentimental value from mom..lol. He hadn't seen it in 30 years.

Thanks for the bore images

Allen

Harold:
Now that I'm back online again.
That second picture is a bit worse than the stainless Cooper 20VT
but the same type pitting for a patch about an inch long.

Wonder what would cause a supposedly stainless barrel to do that.

Harold and George, about the borescope pictures of the barrels. In my experience, that pitting type of damage looks like the corrosion/erosion from hot combustion gases from firing. The network of 'mud flat cracking' that is sometimes seen is usually from thermal fatigue caused by rapid firing and getting the barrels too hot.
