Self chambered shoots bugholes all day long with factory hornady 143 eldx. It’s my favorite stick in the safe!

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.

That’s why I ended up having to go directly through Zermatt, couldn’t find stock anywhere. I’m at 10 weeks now, hoping this week it will be ready

Post your Bighorn Origin builds here.

Mine is another masterpiece by Jon Beanland.

Bighorn Origin
#3 Bartlein 5R chambered in 6.5 Creedmoor finished at 24”
McMillan Adjustable Game Scout in Desert Carbon Ambush
Triggertech Diamond
APA Bottom Metal
Bighorn 20 MOA rail
SWFA rings
Bushnell 3-12 LRTSi
Flush cups on left side.

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.

John

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.

Nice looking rifle and it sure preforms well.........good luck on your hunt !!

yeah I had to go through hunts long range, even they took awhile to ship it. Hard to find them right now

@Stick42 ... I just picked up my Origin from Southern Precision(Bugholes) and they still had some in stock.

Wish I would have went that route from the get go. Already have the deposit and 10 weeks in at this point

I'm trying to get my head around the prefit concept. I'm interested in an origin with a proof carbon barrel. I see that Proof offers a Zermatt pre-fit line, but what I want it OOS everywhere and proof told me december earliest yesterday.

If I'm tracking with how these actions work, could I just put a savage small shank in there and add a barrel nut? Headspacing of course. If so, which barrel nut?

choose which ever looks best to you... but yes you can slap a savage barrel in there. some guys will even red loctite the nut in place (making sure their headspace is $$ first). but honestly proof barrels are an unbelievable bang for buck.

PVA
Keystone
Etc

All do shouldered prefits.

 

[bgrav321]

Which barrel nut do you all recommend if going this route?

 

[IowaGeologist]

Which barrel nut do you all recommend if going this route?

I really like the PVA nut. Have a couple of the coated ones and they're great.

 

[spife7980]

I’ve used the pva and the nss and both are fine, most any aftermarket more than 20 bucks but should be good to go.

 

[6brshooter]

Bighorn, pva, are good to go. I lile the looks of the deadline barrel nut, pretty clean and doesn't scream barrel nut.

Zermatt invisinut if that bothers you

 

[6brshooter]

But that wrench$, lol. Im cheap like that. A barrel nut that had a longer taper and a couple spanner wrench holes would be neat.

 

[gdonley308]

I am wondering how much bolt slop/wiggle anyone else has, with the bolt fully open on their Origin actions? Mine is a long action.

Mines got a fair amount, but it’s never been an issue while actually running the action.

End up getting your action yet?

 

[Stick42]

No, I reached out to them after I hit 10 and they advised they got pretty backed up, which I can understand, and running about 2-4 weeks behind. Said they had a batch heading out for Nitride treating and mine would be in that one. They have been very good about communication. I shipped them my trigger and was confirmed they had it etc. Bummer about delay, but I’m not up in arms about it.

 

[RFutch]

It will be worth it.

 

[levi8599]

Agreed. I just ordered my 3rd for a hunting setup.

 

[b6graham]

same but any action is like that

I'll have my new long action posted tomorrow. finally ready to go.

 

[TheBigCountry]

Still waiting somewhat patiently for my BA. I’m at 8ish weeks so hoping by the end of the month.

 

[gdonley308]

Well my Tikka TAC A1 in 6.5cm has almost no play/slop with the action open.

oops, sorry for the double reply

 

[TM6]

Been waitin with anticipation, where is it?


I've been resisting the temptation to do a LA Origin build for almost a year now, but getting weak in the knees.

[TheBigCountry]

Right there with you. The only thing holding me up from a L/A build is choosing between an Origin or a TL3. I already bought the barrel. Bartlein 30 cal 1:9" 32" finish at .900. Going to be a hoss.

Do it already. Origin for the win.

 

[MPrimo]

Ok ... I'm in. Ordered an Origin action from Bugholes. Have a Proof CF barrel in 308 on the way as well as a KMW Sentinel being painted by Short-Bus. Will buy the barrel vise and tools next week. Would love a 223 bolt head and barrel as well. You guys are responsible for this ...

 

[338LM]

Can someone tell me if a Origin action will go in a MPA chassis without any modification having to be done to the bolt handle cutout due to the swept back bolt handle ?

Just drop in and bolt down, no modification at all.

Now it is getting a bit frustrating seeing that bugholes has them in stock, yet I'm sitting here at around 14 weeks directly from Zermatt and still don't have a notification that it is ready.

 

[b6graham]

You can always order in stock from multiple places if you need it asap.

 

[Zermatt Arms]

The reason they show in stock is that they always have multiple orders in the queue and it fell in front of yours. We always process orders first in, first out. We're working as fast as we can on these actions and will get them out as soon as we have them.

For future reference, it's always better to check with our dealer network to find one faster than ordering directly from us. We're always up front with people on where to look for the fastest turn around.

If you're past 14 weeks, please email me and we'll work it out with you individually.

Thanks - Ray [email protected]

Thank you for the clarification, didn't mean to come off as upset or a complainer. I'll wait patiently in my corner now and post up a pick when my rig is all set up

If not a comp gun, I'd go Origin and put the difference into your glass. You and b6graham almost got me convinced to go 30SM, but still teetering back and forth it and the 28SM, I can't do both.

I'm outta here, already thinking of selling off a couple rifles to fund new builds.

[TheBigCountry]

Got word my barrel is done, just waiting on the action from Zermatt (just around 11 weeks so far).

I do think I’m gonna bedazzle my all black MPA and paint the sucker this coming weekend.
