The argument for more case capacity is for greater range, not higher terminal velocity. Each bullet has a window of terminal velocity which is target dependent where it gives it's best performance. The muzzle velocity, bullet BC, atmosphere and range determine the terminal velocity of any bullet.
A quick calculation says a 110 grain bullet in a 24" 308 would give about 3300 fps muzzle velocity. I'm just guessing at the BC but that should give roughly the terminal performance at 300 yards as the 300 BLK near the muzzle. I think the 300 BLK is the best subsonic cartridge on the market. I just don't have a use for it for supersonic shooting. For many hunters with suitable game at short range it may be ideal.
rsilvers:
Can you give us the dimensions and BC for 110 Barnes bullet? Is it a "lead free" design? So the back tip is a poly insert in a large hollow point? It would be nice if SAAMI would standardize what tip colors mean like NATO does.
I really like the way you present your test results with bullet photos and barrier + gel penetration measurements. What thickness is the door steel, plywood, and drywall?
