Question: what is the difference between a 223 and 308 caliber?
Answer: Because it has a lighter bullet and faster speeds, the . 223 Winchester usually maintains a flatter trajectory. ... 308 Winchester with a 150-grain FMJ-BT bullet drops 3.6 inches after 200 yards and 13.5 inches after 300 yards. It's not a large advantage, but it's enough to make a noticeable difference in long-range shots.
