The stacked bead thing is more of a trapshooter concept. POI on a trap gun is supposed to be high because the target is rising. Lead is built in. The sight picture is generally the mid bead at the base of the front bead in a figure 8 pattern. When Jimmy W referred to his trap gun shooting 40/60, that’s a new one on me. I’m sure Al Ljutic forgot more about trapshooting than I’ll ever know but to shoot the bird at it’s apex is just, weird. When I shot trap I’d try to shoot the singles quickly to establish my timing for when I shot doubles. But I digress.
I know what Al Ljutic says about shooting seems weird. If I can find the book that came with the gun I'll show it to you. I see a lot of guys who brake trap targets before they get 10 feet from the house. But if you wait until they reach their apex, they appear to be stationary targets. And that 1200 fps shot will catch them real quick.
