Several makers of custom bolt actions refer to timing the action to the trigger. I've installed several aftermarket triggers and saw no need to "time" them on M-70s, 700s, or Mauser. What does timing an action entail?

I've built a bunch of rifles and never heard of this on a bolt action. Single shot, yes; bolt action, I'm confused too unless they mean timing the safety & trigger interrelationship.

I believe he is talking primary extraction. If the lugs and bolt handle are not timed properly or at different angles, extraction is very hard.
As far as the triggers go, some aftermarket Remington triggers are set up with a different amount of firing pin fall. Of course if it is not enough, it won't go bang all the time.

This came from the Borden website regarding their actions:


"No Rimrock action leaves the Borden facility without first being timed. Therefore a trigger has to be purchased or provided by customer for the action. Kelbly or Jewell triggers are used in the Benchrest actions and Timney or Rifle Basix triggers are used in the hunting actions. "

He is speaking of firing pin fall. I know that the Jewells and Kelblys have a different amount of fall.

Timing a trigger to an action, means to ajust the position where the hammer engages the sear, so you optimize the fieringpinn fall. This also take away the anoing "point you feel on manny poorly timed rifles, when you open an unfiered bolt.

Try slowly to open a bolt when unfiered, an you most certainly feels a "stop" in the rotation some degres before fully rotated. That is a product of improper timing.

Does "bolt jump" when firing an unloaded bolt action fall into this category?

No.
