Barrel Damage?

[Rocketeer77]

Looking at a friends barrel with the Teslong bore scope this is what we found in the stainless steel barrel.

Does anyone know what caused this? They kind of look like pressure rings with material erosion? Just a guess on my part.

Any help would be appreciated.

Thanks in advance,

Frank.

This is mechanical damage, not from a projectile or erosion. Not from normal usage likely a tool did this somehow

Think it said 243 earlier....just get a chainsaw file and reach in there and smooth it a bit....cant hurt it much more.....

Do I use the file before or after the salt bath?

I believe this subject has been exhausted, and a likely culprit identified.
