For me, station 8 was always a "trick shot", at least after a seasoned vetran taught me his method for busting the little rascals.
The same method works for both houses:
Mount the gun and point at the lower outside corner of the window. Call for the bird and listen for the trap. The bird will beat you out of the house. Swing up to the bird, playing "catch-up" and as soon as the muzzle covers the bird, pull the trigger - but don't stop swinging. Watch out for falling pieces of the bird because they will fall all over you!
This was the only way I ever broke a bird on station 8 before it passed the center stake. I'm no expert but it worked for me.
