Yeah, that part was misleading as well, also a 22lr is a very cheaply made round, and you could easily pull the bullet off the casing with a pair of pliers.
YOu can do that with high powered military rifle cartridges.
Ask me how I know... I had a problem with aftermarket magazines for my 7.62x51 H&K. About the 3rd or 4th round from the end would stovepipe, putting a big dent in the case. I pulled the bullets with a pair of pliers, well two pair, and burned the powder...That last turned out to be the "more than I expected" part... but only because I was living an apartment at the time, and burned several catridges worth on my patio. Kinda scorched the underside of the balcony above. :) Nice pretty purple flame, a BIG pretty purple flame.
