Howa 1 O'clock test

I did a bedding job on a Howa .223 in a boyds stock a little while back, rifle has sat in the safe for a while since due to a lack of spare time.
Recently I pulled it out and did some checks and found it to be failing the 1 o'clock test.
I have checked everything I can think of including the mag box.
What I have found is with the trigger removed movement is almost unnoticeable, I'm not sure if it is just the action being pulled tightly into position or infact there is a small bit of seesawing occurring.
The trigger is not contacting anywhere.
Strangely with the trigger unit fitted, screw only finger tight, results are the same as without the trigger fitted. I assume the trigger is causing the action to flex to some degree when the mounting screw is tightened.

I think I will lap the bolt lugs and test shoot the rifle and see how it goes, it was shooting .35-.7moa before bedding.

Has anyone experienced anything similar?

Re: Howa 1 O'clock test
Ben - I had one rifle that was giving me the same grief. I couldn't figure out why it was doing it. I smeared lipstick everywhere and nothing showed up. I got lucky one day and found that it was the sequence that I tightened the action screws. In this case, it was an extremely heavy, long barrel (knox was bedded out to about 5-1/2"). In order to get it to pass the 1 o'clock, I had to stand the rifle on it's butt, finger tighten the screws, lightly snug up both with a driver, alternating between screws. Once it was secure, I tightened the rear one up to spec. From then on, I could loosen the front one off completely, and retighten it repeatedly, with no discernible movement.

This wasn't a Howa, nor was it a Boyds, but it was wooden and it was bedded as per Nathan. I had also installed pillars and bedded the bottom metal. Not sure if this will help, but it cured it for me.

Re: Howa 1 O'clock test
Turns out all is well.

First group went 0.35" (3 rounds)
The next few went 0.55"-0.7" (5 rounds)

All my brass is now fireformed so final load development should be nice n easy with this one.
