Very similar to the discussions of ammunition going off in a fire or outside of a gun.
Without the cartridge being in a gun it you're just going to have an undirected explosion that's not going to have much force at all.
As a last-ditch self-defense effort you'd be a gazillion times more effective by using the Red Ryder as a club. (Or, since it is the season, you could use it to shoot somebody's eye out.)
