[QUOTE="Deleted member 107796, post: 1581051"] I'm glad you added this because my earlier post was a bit confusing. The left image above, is an example of hi precision and lo accuracy. Let's leave out the gun and shooter variables and just look at the grouping, say, the gun is in a mechanical vise and we are shooting loads that are exactly the same. Do the examples of accuracy and precision, above, make sense for this condition? The grouping defines the accuracy (how close is the group about bullseye) and precision (how tight the group is) of the system. When you add the shooter variables, then your grouping will still be defined this way. In other words, precision and accuracy are only applied to the grouping. This addition of the shooter is exactly why an addition of a few rounds (5 shot test group vs 3) will add more real statistical info to how you are shooting, since we all pull to some extent when we are holding the rifle. IMO, unless mechanically held, ladder tests need to have more than 4 shots per charge. 5 is better. [/QUOTE]
