Tikka T3X Failure to Fire

[Rugger7622]

Well.....I'm at a loss. Shot 40 today, my reloads, new box of primers and had 23 FTF!!!! To recap:

1. TIght chamber - bolt won't close oi Forster go gauge without tremendous force
2. I swapped firing pin/spring from another tikka I own and still had FTF
3. Gun has been moved to 3 different stocks, none better or worse
4. Fired brass only grows .001 and as measured on a Whidden case gauge die is at SAMI 0
5. Primer strikes look solid, not light, 50% of rounds fire on a bolt re-cock
6. Using CCI 450 SRP

Gun shoots lights out, just not sure where to go from here?

Do I buy another bolt?
Do I pull the barrel and move the shouldered nut out a bit to give the chamber a bit more space?
Do I try some different brand primers with softer cups?

You've done a lot. In your shoes, I would fix the known issue (tight chamber), even if I don't understand how it could cause the problem. With a barrel nut and chamber gauges in hand, it's a free and fairly straightforward fix.

Thread 'Tikka Barrel Removal and Install Tool Swap Thread'

May 22, 2023

Based on the discussion from the Semi-Custom Tikka thread, I want to offer up my tools that I'm no longer using to others to remove their factory barrels and install new ones.

Here's what I've got and the cost to replace:
Wheeler Action Wrench #1 - $80
PMA Gen II Barrel Vise - $90
Bugholes Tikka Internal Action Wrench - $100
Torque Wrench (up to 80 ft-lb) w/ bit - $50
Creedmoor Go Gauge - $50
Volquartsen Pistol Case - $30

Full cost to replace = $400

I think some others might be willing to include go/no-go gauges if needed. If there's other items that are needed, feel free to post below...

As mentioned before I would fix #1. With it working so much better the other day I’m not convinced this is the issue but it’s something you can do for free.
I might have a spare 223 bolt in my stash of parts, if I do I will be happy to send it to you so you can try and see if that helps before you look to buy one.

If you have a space bolt, I would love to try it. DM me and we can work out the details.

Two things:
1) I would correct the tight chamber, as others have said. With a Remage-style barrel nut and barrel, it's super easy to remove, inspect, and re-install the barrel so the bolt closes snug, but not overly tight, on a GO gauge. Torque the barrel nut to 80-100 ft-lbs, and then move to stage 2.
2) If the problem persists after the re-install of the barrel, I would want to be very sure whether the problem lies with the handloads or the rifle. You have mentioned having the same problem with factory ammo as well as various handloads. If you can confirm that the problem persists with factory ammo, then the problem is almost certainly being caused by some issue with the rifle.

Sounds good, I did shoot a box of factory last week with no FTF and 20 reloads with 1 FTF. Today was all my reloads, nothing special, full length size, prime, powder bullet, shoot. Today was with both Hornady brass and LC brass both of which had been fired before in this gun and I had FTF with both brass today.

All primers have what appear to be full primers strikes, which makes this even more confusing to me. I can't for the life of me, figure out why a tight chamber would lead to FTF's.

Here are a couple pictures, the one with 3 are FTF’s that went on the 2nd try. The single didn’t go off on the second try. Primers looks slightly off center but well struck.
