You might be surprised at what some people will try.
Nope I wouldn't be surprised - that's why they have the Darwin Awards. About 4 years ago a couple of bright lights from south of the border were working construction in Athens GA (about 50 miles from Atlanta) when they had trouble with the hydraulics on the bucket of their front end loader. They shut it off (with the bucket raised and full of dirt) got under the bucket and disconnected the hydraulic line. Scrunch. Both DOA. Look at it this way. If someone can't harden steel without damaging themselves, what are they likely to do reloading? Would you want to fire one of their reloads? I wouldn't.
