Would that be flatter shooting than the 6.5-300 Weatherby Magnum at 500 yards and 1000 yards?A 300RUM will push a 101g Hammer Blackout @5000fps. My 300wsm shoots 55g sabots at over 5000fps.
Backfire on YT has a video showing the flattest shooting cartridges, 6.5-300 is at the top...
What would be a better elk and moose gun between the two?
