Re: Savage 10 sear not catching when bolt closed fast.
I had this same problem with my accutrigger. It is a common problem as I posted the same thing and got a handfull of people say they had the same thing. I disassembled the trigger and figured out what was happening. It is actually the safety feature of the accutrigger kicking in preventing what would be some what of the bolt equivalent of a slam fire.
If your accutrigger is set really light, it doesn't take much force to move the sear and release the firing pin. By forcing the bolt forward and slamming it in place, you are placing enough force/moment on the mechanism to release. I wouldn't recommend it, but if you were to hold the blade on the trigger to the rear while you slam your bolt down, the weapon will fire. I took a dremel tool to my trigger and made point in which the sear grabs more pronounced and eliminated the problem. I polished it afterwards and it worked like a charm.
