Bore Scope: What am I Looking At?
I got a cheap Teslong borescope as a gift. Pics aren't great but it was interesting to stick it down some of my milsurps.
I'm not entirely certain what I'm looking at, though. Click on pics for bigger versions.
Here's a shot from a Yugo 24-47 that was rechambered for .308. I include it only because the barrel has only been shot a couple times so it's pretty clean:

I think that's what a "perfect" bore should look like.
OTOH, here is a Mosin-Nagant M44. I'm guessing this is pitting from corrosive ammo?

Here is a 1926 Mosin Nagant...same issue I think:

OTOH, this Mosin Nagant 1938 Carbine looks pretty good:

And my 1968 Finn looks great:

Alas, my 1891/30 seems to have some rust and other unpleasantness...which is disappointing because at one point I cleaned the hell out of it and I've always done ammonia + cleaning after shooting surplus through it:
