A 12" Grendel shooting the 123gr ELD-M at 2280fps mv has these metrics at 300yds:
300yds 1799fps 883ft-lbs
A .44 Magnum shooting the Federal 240gr JSP at 1230fps at the muzzle, has 806ft-lbs (at the muzzle).
In ballistics testing on calibrated gel, that 123gr ELD-M will penetrate well over 24" and is still expanding at that speed.
I salute you for the quality of your contributions to this thread. That is a magnificent piece of useful information!
