[QUOTE="Roadrunner, post: 259, member: 115"] Peter, Remember that you can only really accurately shoot a rifle bullet out until it drops below the speed of sound. As it's dropping through the sound barrier, it becomes somewhat unstable and therefore less predictable. Groups shot when the bullet goes sub-sonic have a much larger MOA then groups shot while the bullet is still supersonic. There are many different factors that affect when a particular bullet load will go sub-sonic: altitude, air temp, ammunition temp, humidity ect. So the exact range at which this would happen on any given day is challenging to predict. But as far as any humane hunting goes, at extreme ranges you always want to ensure that your bullet stays super-sonic. Whenever you hear about the military shooting a fifty cal at say 3000 yrds, it's that they're probably shooting at vehicles and MOA accuracy doesn't matter as much with such large targets; esp when you're shooting many rounds (such as from a machine gun).
