Hey guys I’ve read different things on the subject and wanted to see what your opinions are. I just got the email that my bighorn SR3 is done, I have a tt diamond that’s going in it. Should I send the trigger to bighorn and have them time it to my action? I have a tl3 with a cadex 2 stage that isn’t timed that seems ok but not sure if it’s worth having them do it.

just wait until you get everything in hand and try it. if you aren't happy with the bolt close (too stiff) then send it to bighorn to time for you.
what they do is shave material off the cocking piece of the firing pin assy
or you can take certain measurements (get them to clarify for you) and tell them and they'll send you a modified cocking piece. that's probably the easiest route. it involves measuring the firing pin protrusion

Try it first, it might not require any timing. If it requires a lot of cock-on-close then you would get a smoother feel by having it timed.
To measure the amount of cock-on-close take a measurement of the firing pin protrusion from the bolt shroud while the bolt is not in the action. Then take the same measurment while the bolt is in the action and closed. The bolt closed measurment should be slightly more protrusion. If it is more than .010" increase from the first measurement to the second, I would have it timed. I have seen some with as much as .040" cock-on-close. This made for a very noticeable and heavy closing feel.

I timed TTs to my Origins with a cheap set of walmart files. Extremely easy to do yourself and no issues afterwards.
@reubenski had some detailed instructions, somewhere in the middle of the Origin thread, that I followed. If you look there it explains how far to go. Just make sure you file it at the same angle it starts out at.

Just measured my Bighorn Origin with a TT special. The measurement difference between an open bolt and a cocked bolt is .024”. Might look into having it timed.
Thanks
well i ordered my action direct so it came with the action did
normal reports for sending trigger and action are they get shipped same day as received
They have the action it hasn’t shipped yet, thinking of just sending them the trigger and having it timed before they send me the action. May save a little time and money
Do this. You'll be FAR happier than if you didn't. - Ray
