Tikka barrel swap

[Matt5266]

I'm completely new to swapping barrels. I have Tikkas I just havnt removed barrels yet. I'm excited about the whole idea though. Is there a list that shows barrel faces that will work with other cartridges? Do I need a whole new bolt? Bolt face opened up? I assume I would need a new bolt release at the very least?

I'm looking to spin off a 3006 barrel and wanting to get a 22 Creedmoor. Not sure how much it is going to take as far as swapping parts, aside from a new barrel obviously.

Any help is appreciated.

Thank you

A pic for attention. T3X 18' .223. waiting for a Rokstock.

New barrel is all that is needed for that. You could do the short action bolt stop and magazine if you want but you don't have to. Short action cartridges feed fine from full sized tikka magazines.

If you’re doing it yourself vs sending to a smith, you just need the basic tools, a good barrel vise mounted to a sturdy surface, and an action wrench.

However, my advice would be for removal of a factory barrel, I use a Brownells Universal external action wrench. For spinning the new barrel on I switch and use an internal action wrench available from various smiths.

Tips for removing the barrel:

- you never know how much loctite was put in at the factory so apply some heat from a heat gun might be helpful.
- use a 3’ section of steel pipe as a cheater over the handle of your action wrench.
- use a dead blow hammer for a few impacts on said handle, I have found the impact helps get you started. Just a few knocks.
- inside the barrel vise, coat that sucker with brown sugar. Crank it down as tight as absolutely possible. For me this is the only thing that works to prevent the barrel slipping and spinning in the vise. Strips of leather, etc will just get destroyed. Brown sugar.

A good barrel vice, an internal action wrench, something for an external wrench to break the barrel free, and a torque wrench wouldn’t hurt. A set of headspace gauges wouldn’t hurt, I have never had a factory take off be out of spec but I know after market Prefits from some manufactures can be a gamble there.

I have changed a bunch of them with one of the eBay internal action wrenches it seems to work fine. I am using the SAC barrel vice, it’s the cheaper one I think it’s called a bravo or something like that. For the external wrench I just made my own crude one from some 1” aluminum bar stock and a couple bolts, no pretty but works great and provides a lot of clamping power and leverage. I have never had to heat one or use a hammer to break it free, they just spin right off. I’m just wrapping the barrel with some heavy paper and using the right bushings in my vice, without any slippage.

On the rifle side a short action bolt stop and M or M+ mags. As said above it will work with your long action bolt stop you currently have as well. I haven’t used any long action mags with short action cartridges so I can’t comment on that.

Some good advice on how to remove the barrels has been given here. The only thing I will add is that I use drywall tape wrapped around my barrel and action to 1) get grip and 2) prevent marring. I am 5-5 so far using that .

To answer your question about what bolt faces go with what cartridges, here is a very brief summary in regards to Tikka actions only.

1. 0.378" bolt face: This is for the 223 family of cartridges (223, 6X45, 7TCU, etc.). It uses .223 magazines and a short bolt stop (bolt release).
2. 0.445" bolt face: This is for the ARC/Grendel/PPC family of cartridges (22 ARC, 6ARC, 6.5 Grendel, 6 PPC, etc). You can also use it for 6.8SPC, however it will be slightly oversized for that as the 6.8SPC bolt head is 0.422". Tikka does not make a factory bolt in this size. In order to get it, you will need to have the 0.378" bolt opened up, or have the 0.473" bolt modified with a bushing, both of which can be done by a good smith. For these cartridges, your best bet for reliable feeding is to put the rifle in a chassis and use Accurate or MDT magazines designed for the ARC/Grendel. Short bolt stop.
3. 0.473" bolt face: This is where we can have either short action or long action cartridges. It is the most common of the bolt face diameters and is used for the 308/Creedmoor and 30-06 family of cartridges and all of the variants thereof ( all of the Creedmoor cartridges, .243, .260Rem, 7-08, 358 Win, 338 Fed, all of the BR family, 25-06, 280 Rem, 338-06, etc). The difference is whether you use the short action bolt stop and magazines (308 family) or the long action bolt stop and magazines (30-06 family). There are plenty of wildcats that have been developed using this bolt face diameter as well.
4. 0.540" bolt face: Also known as the Mag bolt face. This is for the belted and non-belted "magnum" cartridges, such as the 7RM, 300WM, the PRC family, etc. For these, it is most common to use the long bolt stop and long action magazines, even though the 6.5 PRC is billed as a short action cartridge. It benefits from loading it long.

There are a couple of bolt face diameters larger than the 0.540", but they will not work with Tikka actions. If you want a more comprehensive list of what chamberings will work with each of the bolt faces, a bit of Google-Fu will lead you down the right path.

Thanks all for the responses. I have read several posts on here as well as Dioni's write up on it so I understand the process. I was mostly curious as to what all would need swapped out to take the 3006 to a 22 Creedmoor. I could not find much info on bolt sizes and faces, like what cartridges can work with the same bolts.

If I only need to swap the barrel and possibly get a new mag and bolt release that would be awesome.

This is what I was looking for thank you. Ha I tried some googling but I'm no master and you provided more info here than I could find.

Based on your response sounds to me like my current bolt will work, just need a new barrel now.

Yep, new barrel is technically all you need, however if it were me, I would swap the bolt stop and magazine as well.
While the Creedmoor cartridges will feed from the LA mag, there is a lot of room in there for it to move around, which may, or may not, introduce a variable that prevents 100% reliable feeding. $40 is a small price to pay for a mag. Plus, if you don't ever plan on going back to the LA, you can easily sell the mag as a lot of us are always on the lookout for cheap spares. Post it up for $35, shipped and I am sure you will get a buyer.

Lots of good information above and in the barrel swap posts you should look up.

If you are good with a hacksaw, cutting 3/16” deep just in front of the receiver all around, leaving a thin 1/16” strip untouched, will release the vast majority of the pressure on the threads and the barrel will unscrew much easier.

I have a used short action bolt stop I'd sell if you are interested.

I've swapped 2 tikka barrels: one on a brand new 270 T3X to 35 Whelen AI conversion and another on a "well worn" T3 243 to 6.5 creedmoor conversion.

The barrel was a bugger to get off of the new 270, but nowhere near as hard as the used 243. I had to make shoulder relief cuts on the 243 barrel or it would still be on the action today. If you run into that much difficulty removing the barrel, just remember that option as a last resort. It ruins the old barrel, but makes way for the new.

When I buy a new Tikka, I always break the barrel loose, use some solvent to remove the bonding agent on the tenon, and re-torque to 100'# with anti seize. I've had some that were heat cycled god knows how many times, and I had to have a smith relief cut the barrel for removal. I have a very good barrel vise, inside and outside action wrenches, and I couldn't get em broke. I think they have a 400# worlds strongest man competitor torquing barrels in Finland.

This summer I did two Tikka actions. One was a 270wsm and the other a 270 Winchester. I used a 21st Century barrel vice with a Wheeler barrel wrench #1. I was worried how hard they were going to be based on the horror stories I had read about but they were actually not that bad. Removed those two barrels and replaced with X caliber barrels with a barrel nut and both rifles are load developed and hunting as we speak. Was easier than I thought it would be.

I recently helped a good friend swap the barrel on his rifle. I loaned him my tools and gave him instructions on how to do it.
He called me a couple of evenings later and told me he couldn't get it off. He said he tried a 3' cheater and was continually beating it with a dead blow and it wasn't moving. I hopped in the truck and went over to see if I could help.
What I found out after some troubleshooting is that he had wookie-torqued the action wrench on the action right behind the barrel/action junction. Essentially, he had introduced a clamping force on the threads. As soon as we moved the action wrench back a little bit, put it on only tight enough to keep it from sliding, and put a little heat on the action, it popped free after two hits with the dead blow.

Just something to keep in mind.
