Bore picture questions

[varget204]

I have some newbie questions about bore pics from my 30-06. The gun is 22+ years old and has seen approximately 400-500 rounds over its life. I took these pics after cleaning and need some input. Maybe there is a condition in the bore that is poor or maybe my cleaning practices need to improve (that's what I'm hoping).

Pic 1 & 2 both look good to me, but maybe from the light being better closer to the chamber.View attachment 1213651View attachment 1213652

I get to Pic 3 and it looks much different

On Pic 4 a second dark line appears.

Pic 5 shows a break in the discoloration at the muzzle. Definitely questioning my cleaning at this point.

Pic 6 has what looks to me like pitting? The only spot I noticed when running the borescope.

Any suggestions? It's pics 3 & 4 that have me puzzled. I used Hoppes No. 9 on patches and I also ran a light dose of Butch's bore shine too.

Use Copper eliminator on a patch, or a patch on a nylon brush,those Pits are in the steel,Magnified Many times, by your borecam

I was out again this morning with the M70. It's back to shooting good even in windy conditions. Video shows hits on my 18" gong from the bench at 300 meters. I fired as fast as I could get the 10x Leupold centered. I fired 90 shots total practicing basic field positions, sitting , standing, kneeling. Just finished cleaning the gun, copper buildup is light.

Good shooting, that is a Keeper
