Terminal velocity
I'm watching this TV show and they're doing a test to see which round has better penetration: 5.56 or 7.62. They're firing at 16 acrylic plates packed tight together but they're only firing from about 10 yds. It got me wondering: at what range does the average rifle round reach it's terminal velocity? It seems to me that, at 10 yds, the round is still speeding up. Am I wrong? It the round going as fast as it's going to go as soon as it leaves the barrel?
