I just got into bedding 6-7 years ago and have only bedded five rifles. One was a Mod 70
copy and the others were Savages, with all being wood laminate. None of them were bedded
past the recoil lug and four out of five shoot under MOA. The Mod 70 copy had issues to
begin with, but bedding did improve groups.
The X7's stock/pillar placement is similar to a Rem 700 (as opposed to Savage/Stevens) and
could be done similarly:

If you are bedding the factory stocks which are already pillared, just dremel out around the
pillars and where the stock meets the rear of the recoil lug. It is my understanding that the
epoxy will not adhere all that well to stock plastic so it's a good idea to shallow drill a few 1/8"
holes at different angles to create "mechanical locks", which you want there and NO WHERE on
the receiver! Make certain that there is no place the epoxy will get into a hole or slot in the
receiver.
I may use the tupperware stock and if so, plan to do it as described above. It will look similar
to the 3d photo on the page link above. But also got a laminated Boyd's and will probably end
up going the whole pillar route. (NOT going to use 15 minute epoxy, though......I work too
slow. ;D
You can also incorporate the stress free bedding described on the following page:

That's a beautifully perfect full length pillar/bedding job, (full length of the receiver, that is)
but you really only need the areaaround the pillars and recoil bedded for good accuracy
