It's hard to explain.
You have to feel a rifle with tuned bolt and then feel yours again and then you would understand immediately.
It's about synchronizing the travel of the cocking piece to the trigger so that the bolt closes as easily as possible.
Stock parts always have tolerances built into them to guarantee they work and with those tolerances come extra travel that creates bumps.

Did you screw in the barrel yourself? How did that go?

Very easy. Just used a barrel vise and I got a rear entry action wrench. Torqued it on to 75 ft lbs.

Iíd consider a bit taller Rings.

While you can not ďseeĒ the item that reduces the light into your PST, it still will not be as bright. Of course you bought a chassis with NV rail, that doesnít mean youíll use NV; but it will not line up if you choose to do so.

Kriller134
I will post some pictures for you showing how a custom action gets timed.
On a BAT Machine action they use a trigger hangar rather than putting the two crosspins through the actions body.
The hangar is just the two crosspins and two socket head capscrews in a tiny piece of good aluminum.
The two set screws positively locate the trigger hangar onto the action.
The crosspins however can be set at a neutral setting or offset generally in 0.005 increments.
The hangars are reversible as well giving you more options.
Why do we do this?
If your first build comes out perfectly from the factory with all of your tolerances exactly on the spot you are good to go.
BUT
If you do any work on the lug abutments the lugs or swap out the cocking piece you MAY have thrown off the timing. Likewise if you change out the trigger it can do the same thing.
By having offset hangars you can tune it back to where you want it.
I have no idea on how this is done on guns without a hangar so Randall will have to explain that.
Oh yeah the normal disclaimer about my photo quality

I install the whole firing pin subassembly with the shroud and cocking piece into a fixture I made for my surface grinder and I move the surface rearward that contacts the sear on the trigger assembly.
Before that, I radius/polish the edges of the bolt that interact with the cocking piece.

Default Rifle build

Hereís a quick video of the difference between an action that has been and hasnít been timed.

The action in the green stock has a Timney Trigger with Randallís work done to it. The other is a new unfired action with a Trigger Tech Primary Trigger. You can see how smooth the first action is, vs the large bumps in the second action.

Do all bolt actions do that, or is it a Remington-only phenomenon?

All bolt actions that I have handled do that.
Not all are easily fixable though.

Yes.
That's exactly what my bolt tuning service is removing.

So after watching the video that NorCal posted, and what Randall posted, there is a slight ďbumpĒ when closing the bolt if I go slow. If I run the bolt at a normal speed, I canít feel it. Randall do you time custom actions or just Remington?

I work on any 700 pattern actions as they are easy to fix.
I can work on other types as well, but I have to look at how they work to determine how the safety works and if it cause a problem.
