Took it out for some more testing. 42.0 gr H4350, shooting 140 ELD, only played with seating depths this time. 0.010 and 0.020 off the lands had 5 shot groups of about a third inch at those depths. Needless to say, I'm pretty happy. And no more light strikes either. Tempted to buy another Origin...

Shot mine both days this weekend too for load development and fireforming brass. Surprisingly, the light strike issue I was having didn't come back. Fired 100 rounds and all went off just fine. Might not send it back to Bighorn just yet then. Also, had many group that shot submoa, and a few...

I'm just going to leave it in

Emailed Ray, gonna send it in after all,next week after one more session for load development this coming weekend. Seems the way to go, like you said.

The two set screws are on top of each other. I assume one is to lock the other.

Yeah, I'll probably just end up doing that

Lighter bolt close. On mine, Jewell trigger, seemed harder to close the bolt than on my Savage TBH.

Shot them an email a few hours ago, will keep you guys posted on cost. Anyone know how to disassemble the firing pin to remove this cocking piece? I can remove the pin from the bolt, remove the two Allen screws holding the cocking piece in, but can't seem to remove the actual cocking piece...

Well, at the range right now doing load dev. For those that are going to file the bolt trigger contact area, do it minimally. I've had three light strikes / failures to fire out of my 50 shots today. Going to contact Bighorn for a new part tomorrow and just use the original sized part.

Going tomorrow morning to do my first round of load development on the Origin. 140 ELD, running 41.2 to 43.4 grains of H4350, 26 inch Kreiger from Keystone. I tested a go gauge today, no headspace issues on mine, although I had it shipped there directly from Bighorn for the barrel job back in...

Chad, that the Livermore CA range?

Thanks, guys, this was a big help, I definitely appreciate it

Just how much the firing pin sticks out. But nope, it doesn't checked. What I noticed though was the "clicked" firing pin protrusion measurement kept reducing the more I filed, so in a way it was as if the measurement with the bolt closed was chasing the measurement of the "clicked" position...

This does NOT change firing position when the hammer drops, correct? Looking at the mechanism, I can't see how it would

Thanks!

Ahhh understood, that's very helpful. Looks like at the click, I'm at 0.070. I'll aim for 0.075!

9 thousandths of pin protrusion out the back? When I have the bolt out of the gun in the cocked position, my dial calipers say it is sticking out 0.082

OK guys, for the timing job, I'm filing until the pin protrusion when cocked and bolt DOWN is 0.090", correct? Currently sticks out about 0.120 on a Jewell trigger

Just saw it as well. Shot John an email to see if my Origin that he did last year still has the specs for any future barrels or if I'll need to send the action back.

Awesome, thanks, I definitely appreciate the help. I'll just make sure to keep it lubed
