I ran this several times with different guns over a 2 day period.
Best run was clean with a Ruger 9mm PCC carbine. 16.66 HF. :)

8 shots rather than the usual 6 was interesting. I had a definite left bias on all my shots. With a Bill Drill I usually will walk the last few shots high and right. This is a good drill to see how a gun and ammo system will track for you. This will become one of my regulars.
