[QUOTE="Mikecr, post: 321371, member: 1521"] Twist requirements are displacemnt per turn. For your example 11:1, thats 11" of displacement per turn. Doesn't matter the barrel length as this turn rate is just what it is, regardless of velocity. Also, bullets are normally gyroscopically stable, or they aren't. So if you make it 50yds without wacking paper sideways, it's gyroscopically stable(marginal, perfect, or otherwise). [/QUOTE]
