Sanding belts? For the stock? Yowssa! Perhaps for trimming a new recoil pad, but I'd never use a belt sander to refinish a stock. Chemical stripper to remove old finish, scrub with small wire brush, wash clean with water, steam out dents, sand it down (avoiding checkering), then several coats of oil finish taken down to the wood between coats with fine steel wool until grain is filled.
Belts were used to do the initial trimming on the recoil pad.. sanding blocks were then used to do all of the final fitting.. no belts or blocks or sandpaper of any kind was used on the stock.. the stock simply got fresh coats of oil and wax on top of what little was left on it from the last time someone refinished it..
That said, I have absolutely used belts on stocks... I have belts ranging from 36 grit (that will hog off huge amounts of material rapidly) to 1000 grit (which barely removes much of anything even when youre trying)...
I also have pro grade/industrial belt grinders/sanders with attachments to match various contours and shapes..
the greatest challenge with a high grit belt on a stock isnt the excess removal of material or screwing up the lines/contours if you do the job right.. the challenge is keeping the high grit "polishing" belt from burning really hard woods.. to avoid burning you just make very light contact, and keep contact with the belt and the surface you are touching very short in duration..
