I said "-exec +", although I concur it was too easy to miss.

Try replacing the "\;" with "+", depending on whether pgm can deal with
multiple arguments.

Which is what

find ... -exec pgm {} +

will do, without piping the data to xarg and without you having to
remember that you really, really wanted to say

find … -print0 | xargs -0 pgm

unless you already know that there are no spaces or funny characters
anywhere in your filenames.
