[QUOTE="LambornLR, post: 1499020, member: 105995"] I start by shooting two ladders through a chronograph. I am looking for the max charge and velocity nodes. I do this in 0.5g increments. After I have a node identified, I'll load 5 rounds of the same charge, increasing in 0.2g increments through the range of the velocity node. Then I shoot groups to see which is the most accurate and has the best extreme spread. This process has been giving me pretty good results. I'll also test some seating depths, if necessary. I built my brother-in-law a 300 win mag this summer. Here is the ladder I shot with it: [ATTACH=full]108616[/ATTACH] Here is the ladder I shot with the CA barrel just a few weeks later--also a 300 win mag: [ATTACH=full]108623[/ATTACH] [/QUOTE]
