And THAT might be his problem. There are several "new" materials out there that are being made into pellets. Finding the exact one that is used in Hevi-Shot loads might present a problem.

Like Shooter said ... NO SUBSTITUTIONS. On ANYTHING. That is ... if you value your gun, your fingers, and your eyes. 
And remember also ... SHOT isn't SHOT. Different materials will cause different pressures and can become very dangerous.
As a side note ....... If I were going to load for coyotes, I'd forget about Hevi-Shot and the other "exotic" materials, and simply load a heavier load of nickel-plated lead. Trust me...they'll get the job done.
