We are blessed here with an abundance of clay ... I was talking with
a guy that has some experience with this and he suggested clay as an
ideal tamping medium . There's a large flat rock right next to the stump
that I might lay on top too .

   Yeah , but doesn't Tannerite require a sharp impact to set it off ? Besides , I already have the Pyrodex ...

 Commercial Tannerite does require a VERY sharp impact to set it off. generally from a high power rifle.  I seem to recall there is a formula that can be set off by a rim fire rifle impact, and a local associate of mine claims there is a formulation he worked with that can be set off by just fuse.  His claim is the only one I have ever heard about "Tannerite", but there are lots of "explosives" formulations that can be made.  Mythbusters supposedly were working on one of their dropped projects when they discovered a very easy one made with very common household products.  They opted to drop that project and swear not to reveal it to the public.  Adam Savage mentioned it in on his TESTED YouTube channel a while back.
 

   There are formulae for sugar , stump remover , and horticultural sulfur ... Those compounds are usually used for "rocket motors" . Though as I understand they are "castable" ... probably not suitable for Richard's purpose unless crushed into a fairly fine (thinking FFF as in black powder) granule . Surface area to volume ratio is the key here .
