[QUOTE="biednick, post: 3059124, member: 123604"] Before you get to the point you have the crosshairs on an animal you need to be able to confidently say "my shot will land within x" of my target at this range". You can't do that with 3, 5, or 10 shot groups. With a stochastic system, like a rifle, you can't accurately predict where a single data point will land. Even if you do everything exactly the same in a perfectly controlled environment with ammo that has no variation from one round to the next you cannot predict the exact place a bullet will land. That's just the nature of stochastic systems. The output is not determined solely by the input. However, the outcome of many samples is normally distributed, so with enough samples you can make predictions with a high level of confidence on the region a single sample will land in. The best you can do is look at a relatively large population and say "x% of my shots will land within this region". Over 30 shots you'll be able to predict where >90% of your shots will land. It is important to consider how the rifle will be used and adjust your testing procedure accordingly. With a hunting rifle 30 cold bore shots makes more sense than a consecutive string of 30 shots. Sure, it takes a lot of time to shoot 30 cold bore shots, but if you want to know how precise your rifle is that's what it takes. [/QUOTE]
