I have all of my books packed. Would someone help me out on a few 16 ga upland/waterfowl loads to determine which I believe is called foot pounds of recoil. It's a modern SXS shotgun with steel shot proofed barrels.

Using a 6lb 8oz shotgun. If shot size is required figure 6 shot.

1 1/4 oz @ 1260fps @ 10,000psi = foot pound?

1 1/16oz @ 1315fps @ 9,600psi=foot pound?

1 oz @ 1250fps @ 8,900psi=foot pound?
