From a 9 inch barrel (2050 fps):
– 100 inches drop at 410 meters
– 41 inches drift at 470 meters
– 291 ft-lbs of energy at 625 meters, so 440 meter max effective range for a 9 inch.
• 300 BLK from a 9 inch barrel has the same energy at the muzzle as a 14.5 inch barrel M4, and about
5% more energy at 440 meters.
From a 9" barrel the 110gr supers should still get you ~ 2100-2150fps. That 2050 figure might be for a 120 or 125gr.
BCM makes a chrome lined 9" barrel. That is what I have on my build. It is right around a 2MOA gun with 110gr Hornady GMX's, maybe a hair more.
