i agree with Pat, with kiln dried wood, one doesnt know what you are getting- was the wood dried slowly in a dehumidifying kiln- minimal heat- and in turn minimal damage to the actual cell structure of the wood, or was it dried in a pressurized steam kiln, where a load of 2x4 can be dried in a fraction of the time- with horrendous damage to the internal cell structure- still meets regs for construction- just no good for archery. i had a piece of chundoo( lodgepole pine) 2x4 - i hit it along the wider edge with a sledge hammer from about 2 feet away- it sheered right off where it was clamped. sure a bit of force- but it should never do that.
wood in the round dries at about 1'' of radius per year- split will dry a lot faster- so it takes a long time- like Pat says!!!
