I pick up free 45 auto brass at the range, along with 9mm, 38 Special, 40 S&W, and even some 45 Colt.
Then I sit down in the garage, load my ammo with powder, primers and bullets (some that I cast myself) from the 1990's and laugh at all the people who still buy ammo from a store for .40 - $1.00 a round (more for rifle ammo).
Keep your GAP. I've got ammo to last the rest of my life in several calibers.
