You haven't shared with us the sort of grouping you are getting. Are you getting perfect circles/triangles? Or perhaps vertical or horizontal groups? I would dig in a bit into the way the mauser action is bedded and try a few things before I went through the hassle of rebarreling.
The way the bottom metal and the front lug meet IMO could be a potential issue. The two pieces can touch if not bedded properly causing a false tightness.
Other considerations:
Check front action screw hole if it is a blind hole for epoxy
Action screw bottoming out in blind hole (too long)
Leupold windage style base windage side screws not tight
Forward screw of front base touching threads of barrel shank
Poor crown, optimal way is to check with bore scope
Action screw holes in stock too small, drill larger so sides of action screw won't touch
Bolt handle touching stock
Mag box must not bind
Recoil lug making early contact in bottom of bedding (rocking action)
Trigger group must not touch stock
Trigger guard must not touch trigger
Uneven bedding--- tightening one action screw to see if the action pulls up at other end.
Action screws properly torqued
Barrel having adequate clearance where it is supposed to be floated
Clean bore

Have you tried any factory ammo?
