    If the load range is say 11.5grs to 12.3grs I will load 5 at 11.5 another 5 at 11.6 and keep going all the way to the max load. Then go to the range and shoot them in their respective groups. When I look at my groups I can see what load gives me the best group not the most punch. Usually you get a flier here and there so you can just use the best four out of five for the initial testing. There are a lot of others things you can do after that for consistency.

    I lode that way so I can take all the groups to the range to see which works the best for me rather than trying them one step at a time. I only use groups of five because I am only looking which load gives me the tightest grouping and work from there. If you have two of the same model .357's side by side you may very well have a minute say .1 or .2 difference in the best working load for each gun.

    I usually load 10 for each gun that I will be shooting them through, it makes the chrono easier to average.

    1+ a full magazine to check for functioning. The extra 1 is for setting my dies to the exact same place if the rounds are exceptional.

    i load 15 rounds at each weight starting at the low end working up to the max (5.5/5.6/5.7/5.8/5.9/6.0/etc...). sometimes i will go pass the max, but not to much. i run 10 rounds arcoss the chronograph and 5 rounds on paper for group. i am looking for the best group and the lightest load that will work.
