[QUOTE="Tangent, post: 1672343, member: 110477"] 10 data points is not enough to perform a detailed analysis. However, based on your numbers, the data is roughly described as follows: ES = 86 fps SD = [22.6, 23.78] range Mean = 2,807.4 fps Median = 2,803.5 fps Confidence Level = 95% Confidence Interval = +/-14.7 fps In general, factory ammo out of my 6.5CM has a smaller SD than your data set. So in my opinion, if you're reloading you should expect better. As others mentioned, there may be other things going on in your test. To put it in context though, if we are looking at a shot distance of 500 yards, we can roughly assume that ~90% of your shots will have a velocity between ~2769 fps - 2,846 fps. This roughly correlates to a differential in drops of ~3.1 inches/0.6 MOA/0.17 Mils. Depending on your skill level behind the rifle, this could be adequate. [/QUOTE]
