Shotgun shells, bigger shot instead of HIGH speeds.

[derbyacresbob]

For each shot size there are speeds of 1350 fps and 1500 fps. The 1350 fps loads will have much less recoil than the 1500 fps loads will have. This list of loads will show how a 1350 fps load with one size bigger shot compares to one size smaller shot at the faster 1500 fps load.

There is also a 1300 fps lead #8 shot load and a lead #7-1/2 1200 fps load to compare.

By putting these loads in this order it really shows how little you gain by pushing steel loads 150 fps faster than 1350 fps. The main thing that goes up with the 150 fps increase is recoil.

Not going to have pass throughs on birds with those numbers. 3" is minimum numbers I would want/need for hunting fur or feathers.

It is amazing the difference in penetration with the bigger pellets (lead). When a BB or T goes 3.70" at 55+ yards compared to birdshot.

KPY uses 20% gel they recommend 1.50" for ducks and 2.50" for big geese, I want 3.70" of 20% gel penetration for shooting coyotes.

The FBI uses 10% gel for testing penetration.

20% gel is harder to penetrate into than birds and coyotes are.
