Not my luckiest day -- Rimfire Factory Barrel Issue

[pilediver]

Just got home from picking up my new rifle.
Installed the new pic rail.
Installed the rings and scope.
UPS showed up with my new bore guide and cleaning rod-rimfire stuff
Ran a couple wet patches and a couple dry patches down the tube
Borescope inserted- Yikes!!

Who did the chambering ?

 

[pilediver]

Factory 22 rimfire

Factory 22 rimfire

What manufacturer? That is ugly.

How did it group? It will never group good again now that you know what the bore looks like.

Tikka
The ugliness is 4-6 inches from the muzzle
Hope they're gonna make it right
Warranty claim on day 1

Wow, I have several Tikka's and recently purchased a Tikka T1X, and they all shoot terrific. However, I have never looked at the bore of any of them with a bore scope.

Nevertheless, I have to agree with you, that looks awful bad, and I would be shocked if it shot well but I would at least try it. Also surprised it made it out the door at the factory. Disheartening to say the least.

You might get the old….”within manufacturing tolerances” line.

 

[pilediver]

I'm going to send it in and see what they'll do, no way I see them saying that's okay. All my other Tikkas have pretty good looking barrels.
If they tell me to pound sand then I will definitely update this.

 

[ShtrRdy]

Let us know how it goes. Beretta hasn't been very good about supporting Tikka.

 

[Coyotefurharvester]

Well you can see they test fired it.

The ugliness is 4-6 inches from the muzzle

What would have caused that then? Both the lands and the grooves are scored.
Some jig to hold the inside of the barrel at the muzzle end?

If I hear that one more time from these smokescreen salesmen I'm gonna develop a tic !!

Maybe a pull-through chamber reamer?

 

[linebaugh]

Normally I see these threads and think someone found the tiniest imperfection and they are losing their minds without testing.
In this case... Ick! I get that the hore scopes magnify things but that is pretty bad.That is plum nasty actually. Id like to know how the reamer go into the groves.

 

[tominboise]

With the finish on the rest of the barrel, you can tell it's an obvious foul up. I am sure Tikka will want to rebarrel it for you. Keep us in the loop.

 

[DShortt]

That is really ugly. WoW.

 

[divingin]

Id like to know how the reamer go into the groves.

OP said it's 4-6" from the muzzle. Crown cutter bushing that seized up or something? Seems a little deep for that though. Ugly, whatever it is.

Doubtful....crown should have been cut on a lathe

How does it shoot?

Probably a dirty mandrell when they CHF'ed the barrel?

CHF mandrell maintence and cleanliness is a must! When you hear about companies CHF barrels with chuncks missing like the old Remington barrel pre-sale it was because they where not maintaining the mandrelss. A mandrell has to be maintained just like a stamping die in terms of diemensions and the number of parts between maintence cycle is very real.

 

[DShortt]

No way would I even bother shooting a new firearm with a bore that looked like that.

No way, no Sir, not acceptable.
