The powder measure setting is not the grains, its just a control for you to load 20 cases with the same increment of powder between each load. You have to throw 2 or 3 charges to settle the powder after you make each change, but that takes no time at all. So now you have twenty rounds of ammo, each with a slightly different charge. Make a list of the increment setting and corresponding charge weight.
We go to the range with 2 targets. One at 100 yds. (that's what is available to me) and 1 target on the bench with your equipment. You have a few extra rounds to get you on paper and now the fun begins. Once your on the paper, NO SIGHT ADJUSTMENTS. You fire a round, mark where is hits on the target on your bench with the load number, i.e., #1. Fire the second and mark it on the paper, #2. Fire them in order. Mark each on the target with its load #. After the 17 rounds, you will see some shots spread out and a cluster of others. Take the middle load for the cluster and that is your basic load-and you can fool around a little from there.
My load worked out to be 61.3 grains, but it is number 55 on the powder meter.
Don't confuse the meter setting with the powder weight.
