Good Post DT. In the past I have sold and traded some of my "Stash" to fund another purchase or purchases. I have also sold some to buy something for Patty. THAT I have never regretted. I would rather see the gleam in her eyes and the happiness on her face than a new Glock, AR15 etc.
And YES, many times the non main line calibers are the way to go when you are going to count on "Found" ammo.
