I have reliable intel that Santa is leaving me a new 700 Tac-AAC-SD and a B&C M40 stock under the tree Monday night. How do I know if the stock needs bedding? If it does, how do I bed it? I am new at this and would appreciate and help I could get.

The b n c stock has a aluminum bedding system that runs through the stock and the action bolts right on the aluminum so no bedding is needed

It would benefit from a skim bed. Bolt the action into the stock and torque to 65 in/lb both screws. Loosen one screw while paying attention to the barrel/forend area. If the barrel doesn't move, good. Retorque that screw, now loosen the other screw and see what happens. If there is no movement at all then the action is stress free. If there is a little movement i suggest shooting some fgmm 168 and see what the groups look like. If there are shots tossed from the group that aren't pulled or influenced by wind then that is stress showing up.

6br hit it on the head, my 5r came with a b&c stock with an aluminum bed. It was shooting 1.5 moa on average untill I noticed the amount of play the action had in the stock. skim bedded it along with the recoil lug area and now its a true .5 moa gun.

1. I do not recommend 65 in/lbs torque for the stock alloy floorplate. 50 in/lbs would be max. The alloy is susceptible to cracking/splitting at 65 in/lbs.
2. Bedding is NOT required. It will MOST likely be beneficial. Install in the stock, properly torque it and shoot it before bedding.
My 5R shot very well in the HS stock without bedding.

multiple threads on here with instructions.
short version
get a lb of devcon steel putty, about 33 bucks
get 2 1/4 x 28 x 3.5 inch long bolts
cut heads off of bolts
buy a can of neutral kiwi shoe polish
get q tips, wd 40, denatured alcohol, plumbers putty/play dough, painters tape
remove action from stock thread in your new action bolts that you made, use layers of painters tape on bolts to center them in pillars that are in stocks, wrap barrel with painters tape in a few spots ensuring action is level in stock, barrel is centered in stock channel and that the action does not rock on block with pressure applied to front or rear tang areas.
prep stock by cleaning and making indents/scratches for evcon to adhere to.
clean stock with alcohol, mask everything off with painters tape, remove trigger from action, fill all voids with plumbers putty, tape off areas you do not want bedded, place 1 -2 layers of tape on recoil lug front/sides/bottom
check all fit again and again until everything is level and no rocking in channel or stock
coat whole action with 1-2 coats of kiwi buff lightly witout removal.
mix up the devcon apply liberally on the stock areas use extra as it will seep
drop the action into the stock allowing it to sit on tape and sit level in stock, press action in stock to seat it. Many wrap action with thape or rubber tubing to hold in stock you decide on this I seat the action, ensure it is level and bottomed out so it is not stressed by a clamping force on my bedding jobs.
let it set up for 15 minutes, start cleaning all excess devcon off, plastic knives and q tips soaked in wd 40 are key here.
let it sit for 8 -12 hrs, break it free ( release agent dont forget it. the longer screws may be tapped with a rubber mallet to assist in breaking free.
Trim and clean up the bedding razor knife, swiss files, dremel or a mill
sit back and let it sit for another 12-24 hrs
reassemble rifle checking level, action /barrel straight in stock etc
Go shoot, enjoy and think wow that was a pain in the ass buit worth it.

Guess i have been lucky never cracked or tore up bottom metal in 20-25 different Remington and savage rifles. Must be luck or non issue. Never broke any dbm that were alloy either

Re: Bedding a B & C M40 stock to a 700 Tac-AAC-SD
I think the majprity of cracked or whatever alloy s probably based off of older rem 700 trigger guards that were pot metal versions. The newer are fairly durable, have a couple that have seem repeated 65 in lbs without issue.
I will say that the majority are wearing badger m4 or ptg steel now, as I like them, think they look nicer, and if soething breaks on one of them I know I had to be doing something wrong.
Good luck
If the op does want to go simple/ less expensive on bottom metal or bdl trigger guards check out ptg as they make very nice products reasonably priced

No. Requires inletting.
Some require less than others. Wyatt's is about if not the only drop in, but has a few detractors, single stack (long) proprietary mags, and several generations due to some teething issues. The generational problems were early on so unless you come across an old mag or DBM its unlikely to be an issue.

There is probably little to be gained from bedding the B&C. I've bedded a few of them and some improved marginally, others did not. I wouldn't do it again.

Was actually referring to just replacement bdl bottom metal. Not looking for detachable mags.
