Dean, after bedding the bases to the receiver, I lap the rings and then bed them.

Pro Bed 2000 works great for bedding the bases to the receiver and bedding the rings. AcraGlas Gel is another good product for bedding the rings.

If you opt for JB Weld, use the original...not JB Kwik.

This 700 is a good example. You can see how little contact there was with the receiver:

Bases prepped and Pro Bed on the bases. Screws in lightly to allow for a bit of wiggle:

Lapping bar set across the bottoms to align the rings while the compound cures:

Bedded bases prior to cleanup and chamfering of holes. 100% contact to the receiver:

Bases are on and the lapping process begins. Notice how very little contact there is initially:

This one also needed the tops done as you can see from the marks from the lapping bar:
