Air died walnut will take about 7 to 10 years to dry completely, depending on thickness, if kept inside of a building.
If you can get it up next to a metal roof it will be ready to use in about 3 years.
I have some that I cut off the farm about 8 years ago rough cut for stocks.
Most of these were taken from the stump end and show lots of crouch and waves.
I have both long wood and some two piece blanks.
Just can't decide what guns to put them on.
One of my old Win 94s, my 1886 Highwall, heck might even do a custom BC.
The long wood I am saving for a special project.
A Win model 70 in 45-70 with a 26" barrel.
