   Don't know what the laws are Over There , but here in Arkansas ... I have several part-containers of Pyrodex that I've picked up here and there . Mostly yard sale stuff . My neighbor has some stumps . One in particular is right in the middle of where he wants his driveway . The plan is to drill it 1 1/2 inches and about 12-14" deep . Load about 2 ounces of Pyrodex R-S with a small charge of BP on top to ensure ignition and pack the hole with clay . We'll use cannon fuse to initiate the festivities . The objective is to split the stump into pieces he can drag out with his front-loader .

 I'd like to hear how that goes.  I may or may not have some knowledge of BP being easy to make firecrackers with, and Pyrodex in the same packaging becoming spinners or rockets instead of going pop.
 

  It's all about confinement . Lots of difference between a few layers of paper and about 8"-10" of solid wood .
