the rifle has about 40 rounds of jacketed bullets and 200 of cast bullet
I cleaned it after each shooting session, bought a bore scope and for the first 2 inches on the same side of all the lands there seems to be pot hole
tried carbon, lead remover , and copper remover and they are still there

your opinion please. I was told if you shoot cast first and after jacketed bullet it weld the leas and carbon to the bore
they don't like mountain but instead they look like pote holes

There seems to be chatter marks along the edge of at least one land as well, might be a candidate for a warranty return.

I had an issue with a brand new Savage 110 I bought a few years ago, near the muzzle all the rifling was destroyed about two inches into the barrel. The barrel was threaded and I can only assume that it happened during the threading process (ripped off the mandrel likely). Apparently they had a ton of warranty returns over other rifles that had the same damage, I sent the rifle back to Savage and they re-barreled it, got it back and it still had damage to the muzzle. Slam them out of the factory no matter what with very little if any quality control. Guns they are making now are junk. Sorry for your hassle.
 
I've done this rabbit hole.. My answer is to never fire a brand new gun without inspecting the chamber and bore. I inspect physically with a bore scope before a purchase or at minimum request a declaration of the condition of the bore. The cost of a bore scope is capable of saving so many issues. If you don't inspect, there is no recourse. It's always buyer beware... If you want a perfect barrel, it's up to you... not the seller. Personally that's a strait forward fix with some JB bore paste and Kroil... Cheers
 
I have a Chiappa 92 44 magnum with a bore that makes yours look like one that won the barrel good looking prize. I bought it new and didn’t have a bore scope. Shot cast bullets with it. Then I bought a scope. Oh my. It was leaded up really bad. Took it to a gunsmith and he did a great job of cleaning it. I have fired only copper jacket since and it seems to be smoothing out.

By the time I noticed the leading, sending it for warranty was out of reach. Hopefully I can get to where I can shoot powder coated.

Sell the borescope and shoot the rifle.

on YouTube I punch in new rifle barrel bore scope inspection and even the top barrel makers showed the same king of defect
my lands on my ii Mac where 2 1/4 inch across so if a lands is usually 50 to 60 thousands you have to divide and then pot holes and crevasses are not even .003 to ,010 thousand
 
The secret to owning a borescope is really simple, If it shoots bad and it looks bad it MIGHT be the problem. If it shoots good (or very very good) then who cares what it looks like? The inside of my tikka 22-250 barrel looks like a dried lake bed for the first 3 or 4 inches but it shoots awesome. so I don't worry about it.

The only instances a borescope has helped me find an issue is inspecting chambers that are sticky or marking up the brass. And helping inspect for crown damage. I primarily use mine for inspecting the carbon ring on rimfires.

My opinion is that it still shoots much better than you do. I highly doubt that would even show up on paper.

Now, put down the borescope and step away from the bench.

I consider this bore to be exceptional at 95 years young


This is the stuff nightmares are made of. I’d say it’s a sewer pipe but then I’d have to apologize to sewer pipes the world over.


Still shot like this once I cleaned it up!

Having seen something like that in a barrel my ocd would be telling me to check that there are no raised points that might scratch a bullet, the negative pock marks can be lived with
I know, I know, that won't make a realistic difference but my one brain would still be arguing with its counter-part

My savage 110 .223 not sure of the model name but it came in a mdt premier chassis, looks like a mile of bad county road for the first 2 inches. Tooling marks in the bore, never knew it was there till I bought a bore scope it shoots sub moa with reloads so not changing the barrel . Bought the bore scope for checking for carbon rings in my .22s
