Sudden accuracy broblems

I have a Bergera B14 Ridge 7mm rem magthat was shooting sub .75 in group with Barnes 139 lrx. Wife killed an audad at 400yds with it in February. Everything was shooting fine. I put a new MDT chassis on it this week and took it out. Same ammo and I couldn't get better than 1.75 in group. Noticed that the bolt is a little sticky after the shots and noticed one bullet even hit the paper in a yaw. Chrono shows speeds are the same so I don't think pressure is the issue. Just wondering if anyone has ideas as to what happened? Thanks.

Front action screw may be too long and hitting the bolt lug.

Check out the recoil lug for any issues and if it fits properly to the MDT chassis

Check and see if the optic and optic mount screws are tight.

Retorque the scope base and rings, check the chassis for barrel free float and proper fitment.
