Major rookie mistake

[LE-28]

Obviously I learned a lot from this mistake, but there was never any danger.

There wasn't this time but you a new to reloading. Now you know what happens when you forget to put powder in a case before seating a bullet.

Know this! You can't count on that outcome (locking up your cylinder) every time with a squib load. Sometimes, especially with lead bullets, they make it completely into the barrel and if you are shooting at a noisy range and not paying attention, and fire the next one with out checking to see what just happened,

you have a bomb on your hands that will injure you and people around you.

Welcome to reloading and stay safe.
