[QUOTE="el matador, post: 1168221, member: 12193"] I think you're missing step 4. He recommends starting 7 to 10 percent below the max, so the first load you fire should be 40.0 to 41.4 grains somewhere, not 42.5. Trying to decide exactly where to start can be a pain. I usually decide on how many groups I want to shoot and what range of charge weights I want to cover, then work backward from there. If you want to go from 42.5 grains up to max and shoot 6 groups you would use .5 grain increments and load as follows: Sighters/foulers (1 shot each): 41.0, 42.0 Groups(3 shots each): 42.5, 43.0, 43.5, 44.0, 44.5, 45.0 Some people like to shoot a straight pressure test before doing any kind of load development so they know where work from. To do that you could simply load 1 of each charge weight above and go shoot them. Once you see pressure signs use the next lower increment as your max load. This can be handy if you're using an unfamiliar cartridge or powder. [/QUOTE]
