I was at the local indoor range awhile back testing published max 9mm Para. reloads on the LabRadar.

Guy walks up and asks what the orange thing is. I explain. He asks if I can chrono his loads. Sure. He comes back with the 500.

The first two shots didn't register because the LabRadar had to be on the high speed setting. The next four measured fine.

Six shots is about all I need in this lifetime.
