For many years, my go-to hunting rifle was a Mannlicher-Schoenauer carbine in 7X57. I shot 140-grain Barnes bullets (the old copper jacket ones) in it.
Over the years, I killed many pickup loads of deer with the rifle and about ten elk (plus a few black bears and antelope).
It killed fabulously and I simply knew that I was slinging the 140 Barnes at 2,900 fps. After all, that's what my Belding and Mull manual said.
Then Oehler announced his chronographs and after a few years I bought one. Little black box and you shot through silver foil screens and clicked the dial, recorded the numbers and looked up the velocity in a booklet/
Surprise!!! My wunderkind was shooting 140s at a whopping 2,550 fps.
I simply kept killing with the rifle. Hey, it worked ... and, after all that is WHAT MATTERS.
