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.

yeah I had to go through hunts long range, even they took awhile to ship it. Hard to find them right now
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.
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.
Bighorn, pva, are good to go. I lile the looks of the deadline barrel nut, pretty clean and doesn't scream barrel nut.
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.
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.
same but any action is like that
I'll have my new long action posted tomorrow. finally ready to go.
Still waiting somewhat patiently for my BA. I’m at 8ish weeks so hoping by the end of the month.
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 ...
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 ?

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
i will shoot a match with it by the end of the seasonIs this what you shoot for PRS?
Finally got a shipping notice on mine that I ordered May 5th!!!
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.

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.
