Yes - the flat behind the recoil lug AND the recoil lug's bearing surface both need to be bedded.

The sides, front and bottom should not be touching.

Most or many, that is, also bed 1" of the barrel shank as well - never onto the tapered section of the barrel, to help support the barrel, due to the short threaded shank. Bedding the entire barrel in the stock is not done very often, anymore. It is secure, but oft times, total bedding shifts point of impact as the barrel warms up with repeated shooting.
