When I measure something, if I don't get the same reading each time, then the tool I measured with is broken or I am.

So, the best way to measure the accuracy of a given load in a given rifle shot by a given person is to shoot enough shots per test group with that load that they're all the same size. If you shoot several groups with the same load that ain't all the same size, only the largest one is best to represent what your and that rifle and that ammo will do all the time. Smaller ones represent what happens when the variables start cancelling each other out.

'Course, if you want to feel good about what you, your rifle and your ammo do once in a great while, stick with the smallest group(s) you shoot.

So, Rebs, I'd shoot 20 shots of each load.
