If you're counting on one pellet breaking a clay bird it had better have some very fast rotation, so that you will get assistance from the centrifugal force helping it to come apart. I used to scavenge used clays at a local range to use in an old Comet trap. I have picked up hundreds with multiple holes that did not cause a chip or come part.

I like smoke, not chips. Centered birds and plenty choke gets smoke.
