I have a lee classic press set up. Use Misourri Bullets. The reloads functions fine in my glock. If I decide not to fire a whole magazine, I cannot pull the slide back to eject the round. I have to fire it to get the round out. It's so tight in the chamber, I cannot rack the slide back. But it feeds ok. I'm using a lone wolf barrel .40 in a glock 33. Am I messing up on a step in the process?
