Reminds me of
my
mom's friend's mother, who quit vacuuming forever after she mistakenly
vacuumed up a bullet.. scratch one vacuum cleaner!
Ow! I'm surprised the round went off, though.
I didn't write this but have had the experience, .22 cal rim fire
cartridge. Pretty much any good whack to the rim can make it go. However,
rounds fired outside of a gun shoot the casing off as the mass has much
more inertia and doesn't go very far. In my case the shop vac sorta
'chuffed' and I had to replace the filter which had ballooned to about
twice its normal size.
