We have no Earthly idea what happened today!

IF the rounds WERE that far apart in speed, you would have Felt and heard a difference in the rounds.

Followed by a sharp pain to the face and head.

Try another chronograph.

This reminds me of the time my cast bullet Nagant handloads posted speeds in excess of 3,000 fps!
