NO BRINE !!
In the 1960s and '70s the was a shortage of wood for gunstocks so Browning decided to quickly get more by fast drying wood by the use of salts. Nobody seemed to know about this but if they took the barrel and receiver out of the stock where wood and steel touched the steel was pitted !! You can't get all the salt out .
Sealing the ends is very important but patience is the real trick. Good air drying takes a long time .You might also think of having the wood stabilized on the smaller pieces.
Things like gunstocks can be kiln dried BUT you would have to find someone who would use the proper schedule. If it's 2.5" thick it has to have a schedule for that .Sticking a 2.5" in a kiln set for 1" will give you problems of warping !!
For smaller stuff there is a technique for drying using a microwave oven but I don't know the proceedure .
