Regarding 1:7 vs 1:9, doesn't the barrel length come into play as well?
A 20" barrel that is 1:9 will stabilize heavy bullets too, about as well as a 16" barrel with a 1:7. Or at least thats what I've been told... so if I'm wrong, I'm blaming it on one of you hos who told me otherwise. [Coffee]

Damn kid is getting old enough and gaining a little knowledge so that his analytical thinking is starting to work. More and more often he will ask a question that throws a wrench into my own analytical gears and locks them up.

Oh I've had knowledge for quite a while now, just too lazy to implement it on a daily basis. Which is partly why I really enjoy this thread [LOL]Quote:

Best read I've seen for understanding the topic (and myths) of bullet stabilization.

In short, the LENGTH of a bullet (and longer = heavier in general) the more air can disturb the bullet. Higher rotational stability is needed to prevent the disturbance. A faster twist barrel provides the necessary rotation.
Think of how much rotation a really short top may need to remain upright if you blow air on it, vs how much rotation would be needed to keep a much taller top stable.
Barrel length affects stabilization only by virtue of loss of velocity affecting rotation speed.

yep. Hence the water reference. Pay attention grandpa! [Poke]Quote:
