Now that you mention it...
A couple years ago I moved to a wonderful spot in middle Delaware, with state hunting land next to the back yard. However, there are neighbors to each side and accross the street, although down a bit. In order to do as much shooting as I like I started shooting .22 CB longs (the CB shorts leave a ring) and I have gone through many a box of CBlongs. In fact I have plinked my butt off. Still do. On occation, as I carry defensively every day, I would go out back and do a short training session on drawing, firing, reloading, and so forth with a .40 or a .9mm, but you are right, gets expensive. Then I bought a $40 soft air gun. Yep it's plastic, but so is my Glock. Shoots little plastic balls, and the one I got has to be cocked every shot, but, the draw, the aim, the shot (up to 15 feet) is all the same. Don't let the toy gun fool ya, when one of the little balls comes back from a hard surface, stings a bit. I really recommend safety glasses. But for draw, point, and shoot practice, followed up with live fire, I really like it. Plus, after an adult beverage, the little balls destroy the slugs that hurt my garden. I'll never tell anyone not to practice live fire with the weapon they defend themselves with, but I will also tell everyone, try one of these little soft air guns for cheap point and fire practice, or just fun. In between, .22 CB longs work quite well too.
