Yes, I do. I shot my first limit of wild quail over him at 5 months in the rolling plains.
He is 15 months old now and I had him in North Dakota hunting pheasant, Huns, and grouse for 12 days this month. In open cover he will get out about 150-175 yards either side (per my Astro 430) and in dense tight stuff he closes it down enough to keep up with where I am. If he is on a runner all bets are off. Here is a pic of him on point.
