Eightbore - I'm all for enlightenment. Did Winchester in fact describe in an owner's manual the adjustment process you described? Fun post, this.

You guys got to help me out here 'cause I'm still skeptical of that little thing. Everyone else survives quite nicely without it. Regardless, whether you have a yahoo slamming the gun shut or a yahoo dicking with the screw every time his wife goes off to the sewing club, the result will be the same - not good.
