Has anyone else tested 458 win mag 500 gr HM for real world velocity with a Chronograph.
I get 2063 fps from CZ 550 25" not sure how long there barrel is to get 2260 fps. Just interested to see if there is such a discrepancy with other caliabers.

Velocity is thrilling,but diameter does the real killing.
