Running Powder Coated Cast Bullets in Glock 20 10mm

I was playing around with some 10mm loads this last weekend and decided to skip the lonewolf barrel and see how they worked in the regular Glock barrel. I used some hard cast, powder coated 200 gr TC bullets with about 11 gr of AA#9. I was surprised how clean AA#9 burns. I had very little unburned powder as well as minimal fouling. They shot great, left the barrel clean (no lead in my barrel), and were accurate enough on paper. Since I was at the indoor range, I was unable to clock the loads with my chronograph. This is a picture of my barrel after about 100 rounds:

Once again you have inspired me. Every once in a while I am in bear country and would like a load like this for my G20. I am going to try this.
