Gunsmithing Barrels and metal defects/inclusions

[M338]

Hi All,I have an aftermarket barrel on my rifle chambered in 6.5 cm,the thing absolutely hammered right from the start sub 1/2min consistently.The past few matches my scores have been somewhat sub par,so I logically blamed it on myself.
On a day off last week I visited the range and my pet loads were showing inconsistencies grouping even though my LabRadar showed very low sd/es’s.
I go back home load another 40 rounds with different charges and lengths and still no love,WTF. I decided to give it a good scrub and take it to my smith to borescope,it turns out there are quite a few inclusions in the barrel steel two major ones at the crown one of them in the groove which are visible by eye.
I have the option of loosing some length off the barrel rethreading for the brake and see how it goes or do I just send it back,what do you guys think?

I’d cut and crown it and see how it’s shooting. Then I’d either have it threaded or use it as a hunting barrel

 

[M338]

The visible ones at the crown.
The mark at 3o’clock is not a ding it shows through the groove on the other side.

You could by a bit and recrown it yourself at home. If you see enough improvement just go pay a professional. Worst case scenario, you make it worse and have to replace it. Best case scenario, you find your barrel is salvageable and have a little more Pride in your rifle.

Cut it back and re cut the crown and threads.

How many rounds on the barrel?

 

[M338]

How many rounds on the barrel?

250 rounds
I’m worried how it’s going to be at 1000,there are several more of these through the barrel.

Pardon my ignorance, but that is a chromed barrel?

Stainless steel cut rifled.

Looked frosty on the phone. Yeah, at 250 rounds you have a case for a rebarrel for sure. I wouldn't even question it here.

In fact I'd want that barrel back home and out of circulation PDQ so it could be fully dissected and analysed.
