Has anyone had issues with installing triggers into brand new origin? I tried installing tt special in my brand origin today and i just could not get one of the trigger retaining pins to seat. In general the pins would barely go in. Is this normal? Any suggestions?

Does it seat without the trigger, what if you swap front and rear pins, do they go in then? Aka, does the problem move with the pin or the hole or both?
They do not seat without the trigger, the holes in the trigger have a much looser tolerance than the action itself. Both pins are very tough to insert regardless of which hole I put them in.
I'm running a BDL setup. I had mine cut for a wyatts box locally and run 6.5 PRC out of it. I didn't have to touch the feed rails, mostly just fiddled with the box and follower so it wouldn't hang up. This was before they had a PRC specific follower. Anyway, it feeds well. If you were running a standard/non-mag bolt face short action round it should work great. Only (minor) complaint is top loading the fat PRC rounds through the ejection port is a learned skill. Should be easier on standard bolt face rounds, but just know theres not as much of an opening there as there is on a Remington 700.
Figured I should throw mine on here. 22 inch 22 creed

Grayboe stock and badger M5 bottom metal from the classifieds. SWFA 3-9 on top. Early in load development but it seems like it’s going to be a hammer. Pushing 95 SMKs at 3200

How did that 7mm/08 shoot out to range? What twist did you choose. Was it a 1100 yard rifle or was it transonic out there? Curious
Honestly, I've never shot it passed about 800 yards, and I've only done that a few times. I don't have access to a range with that kind of distance so I have no idea where my transonic distance would be.
It's a1:8 twist barrel, I don't reload and probably won't in the near future. It shoots factory Nosler Trophy Grade 140 Accubonds excellent, I think it was right around 2700 FPS with those rounds. I shot a little bit of the Hornady ELDX, but it's gotten harder to find and I liked the performance of the Accubonds for hunting which is the primary use for this rifle.
I have wanted a 7/08 for hunting. Just hard to lay down the old reliables from my safe
I hear that. My plan was for this rifle to be my new "old reliable" and so far it has not disappointed.
I am throwing together an Origin build with parts on hand. Hard to order some parts for now. Short action in the safe and I am bored.
Looking at using the Athlon Cronus 56 mm scope, eventually with a Proof carbon fiber barrel but with one of the barrels on hand for now. Magpul Pro or a KRG Bravo stock.
What height scope rings? Would like enough clearance for flip up scope lens covers.
Cameraland has some Cronus combo deals with Steiner MSR, Athlon MSR, or Athlon medium rings.

I had an Origin with a proof carbon sendero barrel and a Cronus scope, with 1.125 rings and it was fine with scope caps. The 1.125 rings are mediums if I remember correctly, but of course ring heights are a matter of personal preference, but those worked fine for me.
Im getting ready to order a Origin for a 6.5CM build. Is anyone running a Proof Stainless Pre-Fit? Would like to see what the Compition contour looks like and how the barrel shoots.
Here’s a Proof Comp in a Magpul Pro. It a heavy SOB but shoots great. Great barrel for the price.

I also posted this in main Bolt Action before I saw this thread
I just got my second Bighorn / KRG Bravo rifle built - The first has a 6.5 CM Steel and 300 WSM Proof Carbon barrel with a TL3.
The second is a Origin / KRG Bravo with a 6.5 PRC Proof CF barrel - Both are extremely accurate and have Tactical Bolt Handles and Timney Calvin Elite Triggers.
Much to my surprise the Origin Bolt sweeps back 45 degrees and raps my trigger finger knuckle (it is a light rifle with the proof carbon) and the 6.5 PRC makes it jump a bit when I fire - It is like a catholic nun rapping your hand with a ruler in school.
The fine folks at Bighorn will help me fix the problem as well as my gunsmith so I am not worried it will not get resolved - we are first going to swap out the tactical bold handle for a teardrop that has a smaller circumference and see it that fixes it. If not perhaps one of the smaller bolt handles like a spiral - but I want to avoid the small handle as I think it would make the follow up shot slower.
I did quite a bit or research on the Origin and never identified the substantial difference on the bolt angle from the TL3 or I would have just got a second one of those. I consider it a design flaw although they got a ton or requests asking for it.
Has anyone experienced this, why would someone want a sweeped back handle instead of straight like the TL3 and am I alone in the way I have my trigger finger placed where this would happen - just curious and would appreciate commentary

Haven't had that problem. I swapped out my handle because the original hit the Whiskey3 chassis. I like the smaller shorter Badger Mini that is in the pic above. I also would have preferred a straight handle. I love this action, but I probably won't get another.
I agree and thanks for responding - the Badger Mini looks like one of the Bighorn Teardrops - I switched to my original post as there seemed to be more responses there - where there are more pictures if anyone is interested
Yes, the handle is swept back on the Origin action to mimic the swept back handle of a factory Model 700 action.
You get most of the features of the TL3 for $425 less. The only thing I would like to see changed on the Origin is the swept bolt handle. I'm being super picky but I wish I had bought the TL3 just because of that.
If you want the swept bolt handle or want to save $425 on your action and don't identify a need for an integral recoil lug.
It's so funny to read this type of feedback. I know it's not a serious issue, but I love hearing the feedback from every angle.
In 2017 when we were designing the Origin, the predominant feedback on the TL3 was that people wanted a swept bolt handle instead of straight. Same goes for the RimX. We hear people wanting straight handles on those instead and others saying the love the swept handle.
At least there are options, right?
Thanks - Ray
If anyone is thinking about which knob to run, I'm a huge fan of the Extended Spiral on my new Origin. Have the Helical Diamond on my first Origin and, while it's still really nice, most likely will be switching it out.
And I prefer the swept handle of the Origin. I asked Ray for a swept handle on the TL3-SR3 and sadly, he politely said no. Rats. But I still love my Origin.
Wow! This is the 1st time I’ve seen it all together. Did you get your gauge in yet?
Lighting is terrible, but you should be able to get an idea.
Vs the Helical Diamond on my other. Honestly, if you want to try the extended spiral and decide you don't like it, shoot me a message and I'd trade the helical below with you.
I just think the straight handles look better. Functionally it hasn't matter and I definitely didn't care enough to spring for a TL3 just for that. Currently resisting buying a long action. Don't even know what I would do with it, just need a spare bolt head and part of me figures may as well get a whole action.
Yessir. Everything seemed to check out. Mags all seem to fit after filing the mag latch. Love the way the rifle feels. Now just need to stumble onto some spare time and a bunch of ammo I didn’t know I had
Can anyone point me to a 223 proof shouldered prefit or any other shouldered 223 prefit for the origin? Or even the tl3? In stock of course.
This is pretty accurate at the moment.
Like always, it's best to contact one of our dealers rather than ordering direct from us. We'll always be happy to give you a list of places to try first for a shorter lead time.
Thanks - Ray

Load development was easy. Wind was unusually calm so I decided to do it at 500. Not picky at all. Biggest group of the day was the 130gr Berger AR Hybrids at .632 MOA. Best was 42gr H4350 behind the Berger 140gr Elite Hunter. That went .498 MOA. Five 5-shot groups with 5 different loads averaged .555 MOA at 500 yards. Taking this one for Caribou in a couple of weeks.

I picked the best charge from my 500 yard load development and put 5 rounds on paper at 100 today to make sure I had a good zero. Wind was gusting hard and bench was really wobbly or it would have been better. Made a .1 adjustment and reset the zero indicator. Battery ran out on my chronograph so I made a guess on velocity and took it to 820 to use the velocity truing function on Ballistic AE. Group was 4.5” low at 820 so I put that in Ballistic AE and it determined true velocity was 2790. Fired one more group at 820 using 2790 velocity and it was centered on aiming point. I think we’re ready for Caribou.

Still loving my Origin. Only change I’ve made is putting it in an MPA ultra Lite chassis. Still shoots. Five 145gr Match Burners at five hundred yards.
