I cant find the proper spelling for that in my dictionary.. is it not the earth spinning underneath a projectile while it is in flight? If I am correct I understand this to make a difference with artillery shells but what effect does it have on a bullet out of a rifle. does it matter at like 1000 yards?

Some one told me that the correalis (spelling) affect - effect?? was the spin on a rifle bullet causing it to move in the direction of the spin. But I believe this to be called "spin drift". Or the magnus effect to my understanding of a previous thread. But I may have miss understood that as well.

thanks

Here are a couple of references for you. The Coriolis effect is negligible with most small arms. The Magnus effect can contribute to "spin drift".

The easiest place to see it is in your toilet and sink. In the northern hemisphere it goes one way, in the southern hemisphere it goes the other. Or so they say, I haven't been there myself.

No, you'll never see it with any gun you're shooting unless you're in the military shooting howizters and whatnot.

I have tested the toilet bowl / Sink rotation on both ends of the equator it is true and I have video.

I spent a few months on the equator in the military. Our sink drains spun down both ways, slow draining too.
