Pulling crimped bullets?

Not a good idea, heat build up, poof! My dad was trying to make hollow points out of bullets in loaded cases one time. He drilled thru the bullet and the heat ignited the powder which then escaped thru the hole just drilled, right into his face! Looked like he had the measles, lol!

Hence I suggested a hacksaw, not a power tool. Cut it under water if you think the hacksaw cutting brass is going to generate sparks.
None of the cartridge cases I've ever cut with a hacksaw got remotely warm or gave off sparks, but no harm in being cautious I guess.
