I submit that, pointing at a clay pigeon 30 yards away with target load invites a much bigger pattern, and a better chance of hitting with something.
A better chance of hitting compared to what, hitting a stationary or slow moving target at a third the distance?
Sure, Stevie-Ray, your pattern at 30 yards is larger than at 10. It may be 30" in diameter depending on choke, but that 4+ inch target is still moving at a pretty good clip and often requires more than a single hit to break the clay. Then you have variables such as angles, wind gusts, leads.
Isn't the horse dead yet?
