It can be used extensively for small game hunting without generating a lot of noise and is non reloadable. A lot of folks figure if they outlaw some guns that they can still use their .22's without getting caught due to the low noise signature.
This happened prior to Clinton's proposed ammo ban/tax and again when Obama came into office. Everyone worried that by executive order they were going to tax the hell out of ammo and so folks stockpiled the .22 ammo too. I'll admit to buying about 20 bricks back under Clinton. Still have most of it. Now I am just happy I did cause it was $10 a brick back then. Now, around here its $25 a brick for the cheap stuff.
