Remage barrel not grouping

[Ranger.1006]

Just installed a x caliber remage 22-250 barrel. Used go no go gauges to set headspace, rem action was trued, after market recoil lug installed. Fitted to a bergara stock, dollar Bill slides all the way to the nut. 1-10 twist 5 r groves. Broke barrel in per manuf. 4 different loads, diff weights. Best group is 3 min. I haven’t called x caliber yet wanted to make sure I’m not missing something. Thanks

When you say the action was trued, were the tennon threads enlarged over Standard spec?

No front of the action was just squared. No threads where touched.

 

[Ranger.1006]

Also lugs where trued

 

[Eric32]

Unless you got a borescope you should send it back for an eval.

Did you do a control test with factory ammo?

 

[Ranger.1006]

Yes. All factory loads. Just checked o give. 2.062. There was a little pop when seating the bullet with the tool.

 

[Eric32]

Might just be a lemon barrel, I would call xcaliber

 

[Ranger.1006]

Will do. Just wanted to make sure it wasn’t something I did. Thanks.

 

[Evintos]

Wouldn't be the first time Xcaliber sent out bad barrels.

 

[Eric32]

I can't say that but also check the bolt lug engagement on the action.

Paint the back of them with sharpie and see If they wear even

 

[Ranger.1006]

90% plus contact on lugs

 

[Eric32]

Then call xcal

Do we assume the scope has been checked and mounts?

 

[Eric32]

Yea I forgot to ask but the scope also needs to be checked

 

[Ironman308]

I would check the scope base along with the scope rings.

 

[Ranger.1006]

Yep in the effort to rule out everything else. Changed out bases rings and scope. Everything torqued to spec.

[Eric32]

Looks like a crooked throat and chamber how does the fired brass look

 

[Ranger.1006]

 

[Ranger.1006]

I don’t see anything dramatic just rolling it on a straight edge caliper saying there is a slight deviation on the neck

 

[Eric32]

There you go

 

[Shooter71]

You can get a scrub mark like that if you don’t pull the ejector. I also prefer a small fortune float over a single dollar one.

 

[Ranger.1006]

Plunger was pulled for headspacing. Extractor still in place. I just colored a bullet used my c o a l gauge and seated the bullet same Mark same spot

 

[Ranger.1006]

I didn’t get to far with the floating. This is a 1.07 “ bull barrel so extra room is limited

 

[2aBaC̶a̶]

Had to send one back because it had no freebore. I have another one that has a single land longer than the rest. shoots good so I never made a fuss.

Gotcha. Seems like you’ve scratched the mechanical stuff off the list. If your concentricity is good there might be something funky in the throat. If you pull the barrel and hold it up to the light your eye will see a faint line where the freebore starts, depending on diameter. If it’s not concentric you’ll probably see it.
And make sure it’s not the barrel hitting the stock from recoil or bipod influence.
