[QUOTE="LongBomber, post: 2436087, member: 14435"] I used to do a powder node first using 20 thou off. Then I ran seating depth testing in 10 thou steps, then finer to tune it in. Now I just start with 3 thou seating depth steps from either max mag length or the lands (alex wheeler method of finding lands). I find the spot where I find 2-3 seating depth steps give me the best 100y groups. Then seat in the middle of that and move to powder testing, usually I go from mid-book up to one or two grains over book max in .2gr steps. Stop if I hit pressure. Most times that will give me a couple nodes, depending on the rifles use I go one down from or the highest node. I take the middle of the powder node and the middle and +2 thou of the seating depth node. I load up 10 of each and see how they group. Shoot each 10 shot group at 300y. Usually that nets me a solid load. There are a few things to start with where I agree with Erik’s videos. Start with brass in a blue box whenever possible, pick bullets known for consistency.
