While a 45 acp can do subsonic as well as a 300 BLK, it's a one trick pony. It can't also fire 110-125 grain bullets at 2350. Nor does it have the sectional density for penetration or resistance to wind that heavy 308 projectiles do, so there is an advanatage there.
I like being able to take a 6 lb AR and go.
So it's cool that you can take one gun, at least three mags and continually change your scope settings? No thanks!
