You cant use a full load or else you could cause case head seperation in some situations. So you have to use a load with a small charge of shotgun or pistol powder and since there is such a small amount you need something to compress it so it lights uniformly. It is not dangerous if you do it correctly it has been done for a loooooong time
Hope that helps
I did Google it and did learn, like you said, it is used for the wildcat rounds. I actually talked to a guy I work with that has a 223 ackley improved and he explained it also.
Thanks for the info.
