Here's a Remington 700 handle on a Mauser bolt - Be SURE a good heatsink is used during welding, to prevent any change to the bolt/boltlugs hardness/heat treat.
Some rifle owners/builders may prefer that the bolt handle shaft lie closer to the stock/action, i.e. in a groove cut into the stock wood to accept it in the closed position.
If so, then the only difference in the prep would be (besides the stockwork) to grind the old bolt handle stub shorter (prior to welding on the M700 handle), so that the upper end of the M700 bolt stem lies closer to the bolt C/L.
(The action/tang may also require a small clearance notch be filed, under the root of the bolt handle)
Just be aware, however, if that's done - the wood inletting for the bolt handle shaft can be TOO deep, exposing the trigger inletting and/or trigger to both view (with the bolt handle raised) and the elements.
