LOL merlin now i dont feel so bad - in the top (screw off part) there should be 4 little rounded rectangle pieces with a round spring that holds them together - this piece is held in place by the top that screws onto the rest of the puller - take the cartridge and push it down into the hole in the middle of the 4 pieces but make sure the screw-on part is not tight or you wont be able to put it in - the spring holding the 4 pieces should give enough for you to push cartridge in and then tighten the top screw-on part down and smack the hammer bottom on the floor several times and the bullet will fall right out along with the powder -- now if the 4 pieces and the spring come apart well sit down and put them all back in place with the round spring and smoke a cigarette in between trying this or you might lose it all - just keep trying
