Just my .02,
Since you're mounting a truck axle to your action, And since the Boyds laminates in my opinion are a little soft especially around the action bolt escutcheons for heavy duty applications like that, especially without some really sturdy pillars installed and even when they are the differing epoxy VS laminate difference in material strengths supporting the weight around those 2 points might be one of those things that creeps into an unoccupied mind.

I would elect to go with a synthetic that already has a full length aluminum bedding block for a solid connection without fears of collapsing or over tightening the bolts into the escutcheons or splitting the wood with action screw torque.
An economical option would be a Choate tactical varmint or a B&C medalist varmint tactical (I guess they still make em). It wont be as pretty as a laminate without a paint job, but you'll never have to worry about it's strength rigidity or durability.
