Bore scope pics...is this normal?

Long story short...Master piece arms barrel, 300 win mag, 100 rounds down the barrel. I bought a bore scope and decided to take a look at my "new" barrel. What I would like to know is...Should I be worried about what I found? Some strange gouge marks in several spots. Heres some pics...

The last few that have the red/orange looking stuff are in the chamber area

IMO it´s just poor machining and/or poor steel quality. I believe the chamber should be smoother than what you're showing.

Yep, poor machining, material quality, and some horrible tool marks. You can maybe get the chamber polished-out, and possibly get the bore hand-lapped by a gunsmith to help remove some of those nasty gouges.

Check out this Lilja barrel borescope video ...

MPA has a half MOA guarantee. I haven't even shot this gun enough yet to fully develop a load to see how it shoots. Should I shoot it for a while and see how it goes, or just ask that they exchange it for a new one? Is this likely gonna be a problem child barrel that fouls a lot and I'm always chasing my tail with I wonder.

I would, I gunsmith buddy of mine, told me not to buy a bore scope if I want to sleep at night.

Ditto! Get your hard earned money's worth. If they are a reputable organization, they will make it right.

Excellent advice! I am not sure if it is still an option but Lilja used to offer a video tape of your barrel purchase for $25 IIRC.

Doubt erases confidence!!

The bummer part is after I did a simple barrel break in, I shot about 30 rounds over my magneto speed and found a really big node with great numbers. So now I loaded up 50 rounds all around that node at varying seating debts to dial it in. If I switch out barrels I'm gonna have to start all over again...frustrating

Only you can make that tough call. I personally would have it taken care of. I don't normally get too excited until I have over 100 rounds through it ... but that's just me.

According to their site they should have already scoped that barrel with video.

Wouldn't be acceptable to me.

Since you've done a break in and 1st step in load development, I would take the next step or two and see how it behaves.

What brand of bore scope is that?
