One would like to assume that all is square, but that is not always the case. Just check it.
I have a Mark V that exhibited evidence of stress at the range. The barrel had been floated, but I was suspect on the action. Since ones scope mounts span the action, I thought a bore sighter might provide an answer.
Installed my bore sighter and made note of the cross hair coordinates with the scope at it's highest power. With the sighter still in place, I carefully loosened and tightened the action screws and flexing was quite evident with checks of the bore sighter. Glassed the action in a fully relaxed state. Now nothing moves as one torques down or loosens the screws, and it shoots extremely well.
Heating or inconsistent torque if one assembled or disassembled a rifle for cleaning would obviously affect point of impact.
Not a measure that I can quantify, but I'd speculate it's quite sensitive.
I purchased a Bell
Carlson with aluminum bedding block for a Zastava Whitworth, (Mouser) The bedding block was not true to my action so I took a dremel and removed enouph material to glass bed it. Mouser actions vary somewhat. The stock you have might be a much better fit being for a weatherby.
