I havent seen any need in bedding a chassis or even some of the old v-block stocks.
Anything with pillars in a conventional stock i bed but i think its more for peace of mind and im hard headed.
I put a Kelbly Atlas in a Greyboe Renegade and since i had to elongate the ejection port, cut out for the bolt release, releave for the trigger hanger in both the stock and bottom metal, open the barrel channel for an M24 profile and went ahead and removed all of the paint from the action inlet it just seemed a no brainer to go ahead and full length bed the action.
