Did two tonight which had obvious issues with the BM deforming when the screws were tight.

Way I've always done it in the past: wrap the sides of the bottom metal with pinstripe tape and clearance the stock as necessary, put studs into the action, install the mag box to make sure it all mates up, clamp the barreled action upside down in a vice, dry fit everything, clearance more if needed, then put release agent on everything, smear the bedding compound in the stock inlet front and rear, then lower the bottom metal down.

About 1/3 of the time I seem to have a problem with breaking out a donut right around the bedding stud. I might not be waiting long enough for the epoxy reach full strength.

I will try taping it all together next time.

Pulling the hinge pin and floor plate is good idea...bedding compound seems to get up into that hinge recess anyway.

Thanks Al!
