That's what I thought.... 3 shot groups. I thought 3 shots period. I was thinking wow.... these guys are good!
I thought everyone used 3 shots (as a group) to check the load for an accuracy load (or node). I think some folks use 5 but after you find out your sweet spot or accuracy node, doesn't most everybody load up a bunch of that particular charge & shoot? Wheather it's 3 shots or 5, it'll still shoot the same POA / POI i would think.

I have a headache.....
