Best way to fix cracked bedding? (Model 70)

The old stuff needs to be removed, and it just needs to be rebedded. Do the same to the tang as well. Research a bit online, it’s not a difficult job. Generally you mask the front, sides, and bottom of the lug when you’re setting up so you have clearance on the surfaces.

There is a definitive answer, and that is no screw torque on the action. Google “bedding studs”. They only serve to align everything. I tape them from the point where the screw emerges from the action, all the way through the stock hole. This centers the stud in the stock hole, and prevents bedding from squishing into the hole around the stud. The receiver screw when torques should touch nothing but the receiver threads l, and the back side of the heads agains the bottom metal.

You’ll have to maintain the elevation of the action somehow so it sits level in the stock. This could be done by leaving a small pad of the old bedding (not the crushed bit of course), or a shim of some sort.
