Those come out of an Elk (right under the far side hide), maybe 100 yards, I'm not getting anywhere near the claimed velocities in the "book" from CFE223. They're very accurate though, quite a bit better than the 200gr NP and cheaper to boot. I am curious about the ECX and Naturalis in the 8mm.
They do work, multiple Elk and Mule Deer, although always left wondering if even hit them, zero blood trails, always finding them 50 or so yards away. I'd never consider them for Bear Defence though.
No bloodshot meat which is a plus.
