I have an opportunity to change out my 30/06 bolt for a 270 bolt that I am getting for free from a good fellow shooter who currently has no use for the bolt as his rifle was destroyed.

I see no problem with changing it out as both are long actions, same length cartridges and importantly same web diameter.

I really like this rifle and over the years have had a lot of the usual gunsmithing done to try to improve its accuracy (including a barrel changeout). No luck - it still remains a 2 MOA rifle.

Might a change of bolt possibly result in a tighter lock up and therefore an increase in accuracy (tighter group)?
