I've loaded my 38's as wadcutters for probably the last 10 years. I just seated the bullet flush with the top of the brass. But I was watching a YouTube Video. This one is Hickok 45 actually. He's shooting 38 wadcutters and I noticed the top of the case is really crimped over the top of the bullet. Is that the way they are supposed to be? I've never once bought wadcutter factory ammo.
