Sorry, shooter- but if you think the BATF is a pain, you have never had to deal with the BATFE. Although to tell you the truth, I would not shoot a stump on my own property- too easy to remove one with an empty 55 gallon drum with no ends- place over stump, sitting on 3 bricks to hold it raised a couple of inches- fill with dried brush, cup of chain saw fuel, match. The draft is incredible- drum will turn straw yellow. Keep adding a branch or two, burn out the stump.
I keep ANFO, cast boosters, and 40% for the rocks that are too big to remove. THEY won't burn!
