[QUOTE="Memberberries, post: 1745088, member: 106647"] Here is how I understand it Most Accurate is "closest to what I aimed at" and is what you learn from one shot steps on a ladder test. It will reflect how close this load is to a standard or what you zero your scope with. Most Precise is "smallest group size" but this tiny group might not be located near your current point of aim and require that you re-zero your rifle. This is obtained from shooting groups and picking the smallest one on the target. Most Tolerant is "shots of this load are least sensitive to minor deviations in my loading" and this is what Audette's method is quite good at identifying. This method needs a chronograph and works quite well with excel or some other data analysis tool but you can do it on graph paper. My personal preference is a ladder test where I shoot 3 shot groups at each step (usually 15 or less unless its a brand new gun/powder/caliber to me). I then take the group size and the velocity measurements and put them in Excel, refine, and repeat. [/QUOTE]
