I bought a 200# Parrott shell from a very reliable dealer and since it was full of mud and didn't have as fuze in it, I didn't really worry about it -much. When I got home I stuck a garden hose in it to clean the mud out and found out that it was still full of powder. When the powder dried I set fire to it and had the same result that Larry did. That day I learned 2 very valuable lessons 1. All because they look safe and you are told that they are disarmed, check them over very carefully and 2. (And maybe even more important) Be sure that they are very well secured before you take off with them. A shell/bolt/ball that big rolling around loose will take a jeep right off of the road when the load shifts.
