I like the Flight control stuff. Within the confines of my home, I feel that it's unnecessary. I do keep the FC stuff handy in case I want buckshot outside the home where ranges may be extended, or stray pellets are a no-no.
Last year I was staking out my mother-in-law's garden for woodchucks. The first coyote I ever saw in the wild came in at 15 yds. (the longest shot in my house) and I hit the SOB three times with a 3" 1 5/8 oz. loads of #6 shot. Well, I'm sure I killed him but he got away. There's a lesson for you "I use #6 shot for home defense" guys. Next time, wombat or dog, they're getting nailed with Flite Control 00.
Cool thread you started, Bob.
