++Bighorn TL3 Builds++

20190410_180123[1].jpg

Just a quick pic from the ride home i like the all black.
 
My TL3 is shipped along with the free action wrench. I have a threaded non-shouldered prefit that I am going spin on with their barrel nut. I need help in figuring out the proper steps to headspace and torque it. I've seen the videos using an action wrench and a shouldered barrel but not using it the with a barrel nut.

I need help in figuring out the proper steps to headspace and torque it. I've seen the videos using an action wrench and a shouldered barrel but not using it the with a barrel nut.

I put barrel in barrel vice(because it makes everything steady and easy to work with), start barrel nut with wrench on it and run it all the way back with a small amount of anti seize on nut threads.
Slip on recoil lug if applicable.
Put a small amount of anti seize on threads if more is needed and start action on the barrel thread.
Slip go gauge on bolt face and screw action on till it stops.
Take nut down to action barely hand tight.
Pull bolt and slip in action wrench then I initially hold action with action wrench while wrenching the the nut on this usually gives me a couple thousandths past the go gauge.
Then I ensure the go gauge still clears and then no go gauge/go gauge with a .002-.004 thick piece of tape on base doesn’t
 
I dont know if that video covers it but on the TL3 slip the headspace gauge rim under the extractor from the bottom when headspacing. This is very important you can damage the extractor or at the very least it may not headspace properly and possibly create an unsafe condition. The TL3 is kind of unique in this so watching installs on other actions may not be of benefit. Very easy to do though. If you have questions ask here in the forum I'm sure lots can help myself included as I have done this too many times to count.

I actually watched the video and it does show this at 4:05 into the video (didn't realize the bighorn guys were the ones who linked the video lol). Still its an important step that can be easily overlooked especially if you have swapped barrels on other actions.

If one does not use a barrel nut system (regular shouldered barreled) do you need to use go/no go gauges? What about the action wrench, does one need to buy one just like the one in the video?
No need for gauges though some will use them just in case. Yes, you will need an action wrench unless you have flats on your barrel to use a regular wrench.
 
Why is there no 22. Cal. Bolthead available yet? Together with vudoo magazines would be pretty cool and I can't quickly think of a reason why it wouldn't work..
 
Might be the difference between rimfire and centerfire. I don.t think a bolt head swap would work as the firing pin would be different.
The bolthead could be longer, the firing pin hits a second firing pin that will fire a 22round


Or just would have to get a different firing pin that you exchange

you would have to completely redesign the action. If you look at any 22lr bolt action the locking lugs are on the rear of the bolt. it would be nearly impossible to make it work in a standard short action.
 
I just read thru almost all of the pages of this thread (again) ;) getting ideas on a paint job for my Envy chassis and wanted to echo some previous comments on Bighorn's excellent customer service.

I recently got an Origin action from them and my FFL promptly lost the trigger pins and scope base screws. I called Bighorn to order some replacements and they shipped them out to me at no charge.

While I know we're not talking about alot of money, the principle of taking care of their customer still holds true and confirms to me that this company is run by pros. My first indication of this was during the order process...my action shipped much sooner than projected.

Kudos to them!!!

BTW, I love the Origin and my next will be a TL3 that I plan to build later this year for a dedicated F/TR 308.

Hey Chili47. That's a sweet looking rig. We appreciate you letting us get you a barrel! If you haven't already, we had good luck with the load below on our house gun.
- Settled on 41.5gr of H4350. Anything from 41-42gr but started getting some stiff bolt lift on the higher end so settled on 41.5.
- 80.5gr Bergers
- Alpha brass LRP
- CCI BR2 Primers
- Jump .020"
Muzzle Velocity was right around 3340 out of a 24" new barrel.
The group below was at 700 yards

I picked up some of those bullets all have to try that load! Very impressed with your guys machining everything looked perfect.
 
Another TL3 LA build in the works. Waiting on a proof CF 300 Win prefit and manners EH1A for a hunting rig. Action has the CIP cut and manners will be CIP LA mini chassis. Should be good running the 215 Berger's on elk and hopefully moose this year! Also picked up a few 3 round accurate-mag CIP 3.850 mags as I don't care for the 5 rounders in the woods very much.

You're gonna love it. We had very similar ideas. I have a TL3 LA, EH1 w/ CIP mini chassis, TT Special, Proof 28 Nosler. Running 195 Berger's.
 
Finally put together and made the maiden voyage to the range.

I know this is a show and tell thread, but if you all don't mind if I derail it real quick to ask a few questions.
I have an origin action that I've been enjoying and was thinking of upgrading next year to a TL-3. How has everyone been liking it?
Any issues in dusty conditions? Being from New Mexico it's always dry and dusty! I was looking at getting the DLC coated with 20 moa, medium tang (unless y'all suggest otherwise) aics mag cut in short action. With either a Mcmillan or Manners stock. With a triggertech diamond. Have them time the trigger with the action. Well using the proof prefit barrels. Then covert my current origin into a 223 trainer.
Anything I should be aware of ahead of time? Or anything I may have missed?

Sounds like a good plan. TL3 + trigger tech diamond have been a bulletproof combo for me. Didn't need to time the action/triggers on either of them and they run great in dusty conditions.

I shot JC Steel match last weekend and they had a helicopter stage that was shuttling shooters back and forth every two minutes. I had my rifle sitting about 30 yards away from the landing pad for at least a half hour. Got a huge amount of dust blown onto it from the chopper wash but didn't miss a beat.
 
Hey guys, I just got an AW magazine and when I insert it and try to close the bolt it is hitting the back of the follower and takes quit a bit of pressure to get it to close. Now if rounds are loaded in the magazine it is not a problem anymore because the follower is pushed down. I was wondering if this is on purpose or if something is wrong and there is a solution.

Thanks,

Edit: I read you can just file it down ever so slightly to get the bolt to slide over?
Double Edit: Took a file and nicked the edge and it is good to go.

Let’s you know your empty.
 
Just Incase anyone needs a pre-fit barrel spun up fast, I’d highly recommend Greg Young at Southern Precision Rifles/Bugholes. His lead time for pre fits is still 4 weeks right now.

This ones a Shouldered 26” 1:7 Twist Bartlein Heavy Palma in 22-250 AI. Still fire forming my Lapua brass, but the forming load shoots excellent. I’ve got almost 200rds down the barrel now. The 10 shot was as fast as I felt comfortable shooting, pulled three. Couldn’t be happier with his work and customer service.

Anyone have ever with brass not fully ejecting? I think I might have bent my ejector or something. I’ll end up with a spent case sitting on top of the next round in the magazine. No particular pattern or order in the magazine but is a pain during a stage lol.

Next time you get a chance at the range, try using the slow-mo video function on your phone to get footage of the ejection port documenting the problem. It does wonders helping diagnose issues like this.

Throw some grease in your extractor slot. It sounds like it's sticking a little bit. If that doesn't work, shoot us an email and we'll work something out.

Thanks - Ray

Anybody run a TL3 in an AX chassis? Does it fit w/o mods? Anyone have pictures? Thanks

Yes I do. No, it requires relief at the tang and bolt handle on the skins.

7086376


Relieved with a rotary tool and sanding drums carefully until a piece of paper won’t get stuck at any point from bolt body down, like relieving a barrel channel that’s contacting. Take down the high spots until they’re not there.

7086379


I don’t have a milling machine so I used files and the same rotary tool to relieve the skins where the tang is too long.

7086380


Clears bolt handle nicely when folded.

I love the combo. This chassis was purchased from Mile High back in March. Recoil lug clearance was checked and is sufficiently deep and makes 100% contact across the TL3’s lug. Great shooting gun.
