My dream hunting rifle...
Patriot Valley Arms full build
6.5 Gap4s
Bighorn TL3 DLC
24" Proof Sendero 1-8" w/Surefire MB
Mcmillan HTG M40A1 forest camo
Badger M5 enhanced bm
Timney CE 2 stage
S&B 5-20 US MSR in .94" ARC M10

Have you shot it yet? Just an FYI, I have a TL3 and used a Timney CE. There is a slight issue with that trigger on the Big Horn actions. I was getting light primer strikes and it wasn't hitting hard enough to ignite the primer. Big Horn knows of the issue and completely corrected the problem, I just had to send them my bolt for a slight modification. So if you haven't shot it and you get light primer strikes and failures to fire when you do try and shoot. That is most likely the problem. It only cost me the shipping cost of the bolt to bighorn and they had it back to me within 8 days of me shipping it to them. Incredible customer service.

Nearly finished, just got the receiver back from Bighorn today, looks as good as dad's and my Tempest did from Chad at CCG. Feels much better. Just need to properly torque the receiver down and add the 419 rail so i can use the Atlas CAL. Speaking of which i don't have an expensive calibrated torque wrench. It's just a $50 tekton or whatever off amazon. I know i don't set it to 75ft-lbs and go. So without sounding too ignorant on the subject, could someone enlighten me?

Set it at whatever torque settings you want, I usually then go back and forth between the screws getting tighter incrementally until the point that it pops.

That’s a minichassis right? If so manners recommends 60 front and 45 rear I think. So I would stand it up on end so the recoil lugs is tight again the chassis pocket and then Work the wrench up between action screws until 45, then move it to 60 and pop the front.

For the bipod rail idk, 20 lbs? Just snug it up to touching and then a smidge more, maybe a 1/5 turn? Tight but not stripped and you’ll be fine.

Arc rings say 55 per both rail cross bolt and top bolt but I haven’t had any issue running them at 45 myself. Then again I stripped a bolt out on one before (what led to my purchasing of a torque wrench) so I’m gun shy with them now on a precarious scope. I went way over 55 lbs though I’ve discovered comparing after the fact.

No i know the action screws i'm talking about putting the barrel back on with the action wrench. Yeah the mini-chassis hasn't changed to my knowledge it's tighten the front then back then torque the front to 65 in-lbs and the rear to 45 in-lbs.

For the love of God, send that stock back to manners and have the ejection port inlet correctly for TL3.. far too nice of a stick to keep it like that. OCD rant over.

😁

Been nearly two years lol it doesn't bother me that much. Shit i didn't even really notice until now. It's never had a failure to eject. It's not entirely done though. I still want an adjustable cheek piece and again have to put the 419 rail up front for the Atlas CAL.

I'm still leaning towards LRI for the ULATCH so it doesn't add anymore weight though it's pricey, i'm sure if i sent it Chad would have no problem inletting the ejection port. Having said that i'm waiting on my PRS2 for my Tempest so that's my only rifle up at the moment.

I run 60 ft/lbs to tighten the barrel onto the receiver.

I had to fix the ejection port on my Manners TL3 as well. Took 2 minutes with a flat file and a round file for the corner radius. I bet you could call Manners and they would send you some matching paint to cover up the area where you filed away the shell and exposed the fill material.

So should i worry about headspace changing from the previous chambering or just go with 60 ft-lbs and run with it?

I don't think you'd see a headspace difference at 60 ft/lbs. I'd just run it.
I was over at Eric Cortina's (World Champ F class) shop over the weekend, and he literally clamps the barrel vise halfway down the barrel and smacks the edge of that barrel vise with a mallet to both torque and un torque a barrel from the action. I asked him how much torque that was and if he cared about repeatability and then he laughed and said he had no clue. So that was pretty reassuring to me that all the talk on torque settings is only important if there's inadequate torque. 50 vs. 75 vs 120 ft lbs- eh who cares- so long as your smith appropriately indicated the barrel and machined the barrel shoulder appropriately.

Kind of embarrassing I didn't think of this beforehand.....

I ordered and received a left bolt / right ejection port action. Bought a LH trigger tech. Should that have been a RH trigger due to the bolt release being swapped? I have a long action true lefty Nucleus on order so not a big deal, just need to get the correct one for this action.

Also on stocks for that action, I have a pending order in with Manners and have no doubt they will get the inlet correct. In the meantime I was going to get a used LH stock and mill the ejection port to the right side just to get started shooting right away. Am I thinking about that correctly or is that action actually a RH footprint and I would need to mill out for the LH bolt handle?

Left a message with Bighorn but they might be out for a long 4th break.

Sorry we haven't gotten back to you, still making the list of voicemails right now....

Since you have a left handed bolt, the configurations for everything (stock, trigger) will be left hand. The trigger does not need a bolt release and the safety needs to be on the left side as it's cut for a left handed user.

For a stock, you're correct. A used left hand stock will be what you need and you'll need to mill the right hand side down for the ejection port.

Please give us a call if you need more information. We'll answer until 4 ct today. Thanks!

I agree with this, and I think that with a properly spun up barrel and an action such as the TL3, you won't see a bit of headspace difference between 60-100 ft-lbs.

The threads are 20 tpi, so 1 whole rotation of the barrel spinning onto the threads is 1/20 = 0.050". So every 3.6° degrees of rotation equates to roughly 0.0005" or a half thousandth. I'll bet if torque up a quality barrel to a quality receiver to 60 ft-lbs, place co-witness marks, and then increase the torque of the barrel to 75 ft-lbs, you won't be able to see any rotation with the naked eye. To change the headspace dimension by 0.001" you would have to rotate the barrel more than 7 degrees which would be easily seen by the eye.

Once the shoulder of that barrel smacks up against the face of the receiver and gets tight, there's really not much more it can go!

Xander3Zero, nice job putting logical numbers to the theory.

I love it so much I have sold all my other chassis and now have 3 ESS chassis some people hate them but I haven't figured out why yet they just work. Fit for the rem 700 was perfect for both the TL3 and mausingfields I use them with. Triggertech and timney ce both fit perfect and safety functions as they should with no rubbing. I had a krg whiskey 3 and a mpa folder that I got rid of both with minor issues that bugged me. The 6 position adjustable carbine stock IMO cannot be beat on the ess. I even use on an SPR 556 build. Every adjustment locks up solid and stays tight. I have one more mpa with a stiller 338 action in it that I am selling and once its gone I will get another ess probably.
