He is in the Army stationed in Fort Riley, KS. He says that the windage adjustment won't allow the bolt handle to open.
"windage" adjustment ? ?
If you/he mean the scope windage turret, then you can either rotate the scope counter-clockwise 90-degrees so that the old elevation turret now points off to the left and acts as a windage adjustment, and the old windage turret will be vertical, and the new elevation adjustment.
That should effectively put the turret out of the bolt handle's way - but I've never come across a Mauser with Leupold mounts which carried a scope so far to the rear that the scope turrets were abeam of the bolt handle - IOW, sumptin's wrong, or we have a lack of communication here.
If you/he mead the Leupold scope BASE
windage adjustment screw head, it can be replaced with a thin-head screw, and a small clearance ground into the top of the bolt handle's root to clear it.
