When I first heard about pillars I started boring the action screw holes larger than before. Glass bedded the screws (with release in the screws). Then I bored the holes to free the screws.
The result was a cylinder of glass bedding around the screws. I have not done that in a long time. I still wonder why that won’t work.
I still bed all mine this way. I bore them 7/16 of a inch and after removal bore the screw holes .250. My guns all shoot very well and hold their zeros
