I’m still not seeing any issue. A bullet can ricochet in any direction. The first thing @[email protected] posted was a video example of a bullet ricocheting directly backwards (nearly straight up I think?), then ricocheting again off the ground and into the shooter’s earmuff.

He showed enough examples and hard numbers for distance to convince me that this could be a freak accident. If you want to change my mind, you’re going to have to provide counterexamples. I’m even convinced that it could happen with many bullets in a row if the shooting was consistent.
