Opening receiver mount holes

[Buckshot85]

Looking at buying a bolt rifle that has #6 mounting holes.
Is there enough meat there to open them up to a #8?
What’s a typical charge for doing this?

Unless they are stripped or it’s a 416 Rigby leave them 6-48.....

Why?

Why?

That was my question. Why?

Was looking at a Christensen Ridgeline. You'd like to think that the CNC machining would have the holes indexed properly, but that's mass production I guess.
My NF NXS is a heavy scope and was wanting a bit more holding power. May just go with a rail then.

This I can understand. Rarely are the holes WAY off.

Another option for recoil proofing is to have the base pinned to the front ring. You drill one hole and drive in a taper pin or fitted pin.

Typical charge is $25-35 per hole to have a receiver drilled and tapped, any size.

Off center holes isn't very common on new actions. Used to be more common, but CNC has improved things tremendously.

burris signature zee rings will cure any out of alignment. and not mark your scope.
