I'm still basically a beginner when it comes to picking. I've had my share of success when picking, but just haven't done it that much.
Here's something I don't understand:
With some locks, you've got to make more than just a half turn with the plug to get a door unlocked. You might have to make a full turn, or more.
Sometimes the bottom of the plug will be pretty wide, maybe wide enough for the top pins to fall down into the plug when you turn it after picking.
What do you do about that?
