I just picked up the breech lock challenger kit and started to put it together. Im not sure if im missing a part or im just partially retarded but i have no idea on how to put the shell holders in. The kit came with the lee shell holders and the picture in the directions just shows them putting the shell holder on top which doesnt look like its locked in. Ive googled this problem and even did a quick search on youtube and still couldnt find anything. Anybody know what the hell is going on?
