Another thing. A 1200 fps load in a 12 gauge, at 21 yards l, has about a 30” pattern with Skeet chokes. With a .410, skeet choke the pattern is a lot smaller. I figure nearer to 18-20” of usable pattern, 24” tops. So 15” center to edge versus 10-12” center to edge for the .410. If I shoot the front edge off a bird with a 12 I will be in front of it with a .410. I cut my leads back almost a foot on crossers. A half a foot at a minimum. But I shoot the bird before the center stake and have a gun which is moving. If I spot shoot it m, I use more lead because I have a dead gun. You can shoot doubles on 3,4,5 with a dead gun, never moving it, if you practice. Pick the right spot, never move the gun, and pull the trigger twice as quickly as you can. It’s timing and having the right sight picture. You need to shoot the .410 just like the 12 mentally, but be more aggressive, less deliberate and with finer mechanics and slightly shorter leads.
