Sticky Bolt

[Jake Leibke]

Have a rifle with a pretty rough/ sticky action. It’s only got about 200 rounds down the tube. Is there a way to smooth out that action?

What action is it?

It’s a fierce carbon rival.

Just bore compound or scope ring lapping compound.
Coat the bolt and while your sitting on the couch cycle the bolt hundreds of times.

Before you get too far....have you checked for bolt contact from the base and or action screws? A screw a few thousandths too long can load the bolt and cause this....and tail chasing accuracy issues.

Gunked up grease in the action will do that. I would clean out the action and the bolt. Quite a few bolt actions want a dry bolt....Then I would contact Fierce before doing anything else.

How is it sticky? Hard to lift the handle? Sticks when you pull the bolt back to chamber a round? Does it matter if there is ammo in the magazine? Sticky when you push forward to chamber the round?

Could be what Wrench suggests, could be a rough cocking cam surface, could be a slightly undersize bolt body that wants to bind, could be galled lugs, could be a magazine that sits too high, or isn't inserted right, could be dirt/oil/crud as suggested by Gila, could be machining chips or dirt inside the bolt binding the firing pin, could be lots of stuff.

So, how is it sticky exactly?

I have but I’ll check again.

Basically sticky sliding action forward and back. Not sticky just lifting or closing bolt. I guess not sticking per say just not real smooth when working action if that makes sense.

Cherry Balmz bolt butter.

I'd pull the barreled action out of the stock and see if it still sticks. There aren't that many ways to get a bolt to stick while just moving forward. If both action and bolt are straight it'd still cycle with only a cpl thou clearance.

That's interesting. I have a Fierce and it is very smooth. Like stated above, remove the barreled action and check if it's still sticky. You can use lapping compound on the bolt and then run the bolt back and forth a few hundred times. Just be sure not to get any lapping compound on the lugs or in the chamber.
