Why firing angle is less than 90 degree inscr r trigerring?

Answer 1

If your firing angle is 90 degrees, then for one thing, you'll never hit anything. But more

important than that, you'd better take shelter pretty quickly after you crank off that

round, because it's going to end up awfully close to where you're standing, if not right

on top of you, when it's done going up and coming back down.
