Bighorn Origin Build Thread

Origin owners who are using a manners stock inlet for a 700...can we talk about whether or not this will for sure work? Heard both ways. Would be nice if I could just buy a ready to ship manners inlet for a 700. Thanks in advance.

I bought a manners eh1 that was ready to ship for a r700 cut. Fit without issue
 
Another fitment issue:
Bighorn is in my XLR Element chassis, still waiting on my barrel.

AICS mag seats fine, polymer mdt 223 mag takes a lot of force to seat, it fit just fine before the actin was in it. Where do I start dremeling?

Just wanted to give a shout out to Ray @Zermatt Arms for another outstanding customer experience. This is an early action (from original preorder) and has several thousand rounds through it and she runs buttery smooth
 
Just finished my "Budget" Build and can't wait to get it sighted in when the weather clears up!

Can any of you guys confirm which Hawkins Precision Hybrid rings fit the Origin action. I wanted to order a set, but noticed there were two mounting/fitment options.

Option A: Factory Remington 700 spacing
Option B: Stiller/Lone Peak

I remember seeing some guys running them, so I know they fit. Just wanted to confirm before ordering.

Thanks for the help

Just buy picatinny rings and skip trying to direct mount them.

Not sure about the Hawkins, but I've researched potential rings from Talley and I'm pretty sure these will work.


To be fair, I've not confirmed that with talley yet, but they are local to me so I'm just going to stop in next time I'm in the area.
 
Mini chassis? And no ejection issues or bolt release issues?
Origin in a t6a gen2 mini chassis, 700 ejection port inlet but came with a bolt release cut

After a little careful hand filing.

I was running a 6creed barrel on it, brass ejected cleanly but they did just glance across that 700 cut. Not enough to alter ejection pattern, but it bugged my ocd.

This was in an ax chassis but recently moved to this t6a. Just finished putting the 3way adj butt plate on, haven't really adjusted yet other than pad height.

Barrel sped up and was testing some slower loads. Shot the old load that had sped up 50fps, but was out of poa on target. Put 1 rd for aiming point and shot 10 more, I can cover 9.5/10 bullet holes with a dime.

Ended up with my 2nd origin. Both rifles are pretty identical. I posted the 7saum before in black and now have the 25cm in green Don’t know why the photo is sideways. Probably going to get a 3rd and throw a 22” proof cf and a gunwerks clymr on it for a light hunting rifle.

mpa chassis
TT triggers
Minox on the green
Razor 2 on the black
Saum in black is rem varmint contour
25cm in green is m40 contour

So are the TT triggers pretty much the go-to, guaranteed option that won't f$ck up the bolt lift?

I've struggled with my Origin pretty much since day one. First had a CG Extreme Mod 22 I wanted to put on it - and the bolt lift was more like two-fisted opening, rather than two finger. Tried a Timney CE, same thing. Tried a couple tuned 40X and 700 triggers, that were 'better'. Ended up with another Timney, but it still wasn't great. And by that, I mean heavier bolt lift than even my roughest Savage. Smooth operation, but ridiculously heavy bolt open and close.

Finally sent the action off to a gunsmith to have the lift worked over, and it was finally 'good'. And about three weeks later, I found that my .223 bolt head was causing off-center firing pin strikes, and leaving wear marks on the firing pin. Bighorn replaced the bolt head and firing pin assy, no questions asked (yay!)... but now I'm back to a 'stock' cocking piece that gives heavy bolt lift again - with the Calvin Elite.

After seeing everyone else gushing about how great their Origins are, I'm starting to wonder if the trigger is what's screwing mine up?
 
I had only used timney before on other rifles. With all the things I was reading I just went with TT from the beginning. My two actions are about 800 apart in ser number. The earlier one has the very slightest COC, but not enough to bother me. The newer one has pretty much no COC. Both of them I can lift with my fingers though. Haven’t had any issues with either of them.

did you time it to the trigger?

As mentioned, had to send it off to the gunsmith to have the cocking piece worked over to get the bolt lift within acceptable limits. Like, literally, a few weeks beforehand.

I'm not entirely sure I liked the results / way it was done, which is why I'm not in a rush to send it right back to have it ground down again.

As I said, I see everyone putting TT on theirs and just gushing about how wonderful everything is - I'm *assuming* they're not having to have a $hitload ground off the cocking piece to make it usable...
 
...other than fucking up the mag lips is less likely to cause an unsafe condition and/or AD.

I've done a fair bit of DIY stuff on my guns over the years; the fire control system (trigger, sear, etc.) is one area I've stayed away from.

I find it kind of ironic, coming from a Savage, that the 'answer' seems to be "go grind on the cocking piece until it works right" :unsure:

If you have a caliper or depth gauge and can measure the amount of firing pin travel when the rifle is cocked, and then cocked and closed Zermatt can send you the correct cocking piece so that you won't have to file down anything. You could also send your action and trigger to Zermatt and they'll make it right for a small fee. Ray's a great guy to work with. One other thing that applies to any action, if bolt operation is less than ideal, always double check your action screw length.

Hopeful it’ll be here before September.
 
Tag for when my action comes in, which I'd imagine will be in the next week or two and the only thing I'm waiting for to put it all together. I'm currently sitting at 7 weeks, and sent my trigger to them a little over a week ago.

Proof Carbon Fiber 24" 6.5CM Sendero
Eotech VUDU 3.5-18 with Nightforce Ultralight rings

I think I still have another 4-5?weeks based on their quoted lead time.

Here’s my build specs:

22 Creedmoor
Bighorn Origin (duh)
1-7.7 Bartlein #3 at 24”
Manners EH-2 Tommy Bahama
TT Special
PTG M5 Flush Bottom Metal
Unsure on scope
 
Here is mine, it’s nothing too special but I’m loving it.

Triggertech Special Trigger
Magpul stock and bottom metal
Vortex Razor 2 4.5-27x56

Likes to load the bullets long. 2.9135” with Accurate mags

Got a 5 shot grouping of .3 moa this past week with it. Just need more practice now.

I have an Origin/25SST barreled action that was put together by StraightJacket that is awesome for operating feel & shooting. Slick movement, easy close & open. Shoots great. I also just recently bought a 6GT barrel + another origin action + a TT Diamond and put it all together myself. The bolt close on that action takes noticeably more effort than on my 25SST setup. Still shoots awesome, just a bit more effort on close. Is this likely due to trigger in some way? Is this something that Zermatt can fix with timing trigger to the action? Would another trigger (either another TT or a Huber) possibly change this?

Before anyone asks about the bolt close/lift without the trigger installed - I don't recall any extra force when trigger wasn't installed. I will be taking the action out of chassis to switch to a Huber trigger to see its effect. When I do that I'll also double check to ensure bolt closes easily without a trigger.

I had to get my TT diamond timed to my TL3. Was getting some cock on close giving it a slightly heavier bolt close. The swapped to a different cocking piece and it’s good to go now. Call Zermatt and they’ll give you the run down.

Just went to order a 223 Origin action from Brownell's and POOF ... all gone. Anybody know who might have one in stock (308 or 223)? My Google search came up empty at all the regular retailers.
