Gunsmithing Timney 510 question

[fw707]

I put a 510 in a 700 yesterday and I noticed the sear seems to be putting a lot of upward pressure on the bolt.
Anybody ever notice this?
I have one other Timney and the bolt is smooth as silk on that action.

Yes, it happens often. They have a heavy sear bar reset spring and with some combinations/tolerances the sear bar sits a little high causing excessive drag. Taking .005" of the top of the sear bar usually solves the drag issue.

Aeon1,
Thank you for the reply and the information!

Another option is to cut one coil from the sear spring
