Old Roper, I think the benchresters started glueing in round receivers to stocks (after making a perfect mating surface by conventional epoxy bedding with a release agent) as soon as they learned heavier bullets torqued (while bullets wend down the barrel) the round receivers loose from conventional epoxy bedding. The 3 position match rifle folks started using sleeves on their Remington receivers in the 1960's for the same reason. That's when I first heard of benchresters doing it. And the barrels didn't touch anything except the receiver face; at least 1/16 to 1/8 inch clearance around it.
Gluing in flat side/bottom receivers isn't needed, but some do it anyway.
