Just to be on the same track here, what is the standard way to measure a group? Assuming its the nice triangle of three shots, what method do you all use? Measure the distance from the furthest out bullet to the line between the other two or measure between bullet to bullet and average or what? For comparison sake while developing loads, i kind of want something that is an honest representation and repeatable to quantify the good from the bad on loads.
And as a side note, anyone have a good reason why some loads print two stacked and there is always a flier an inch or two out? Some loads do it, some dont?
