[QUOTE="dougduey, post: 2012468, member: 33159"] I follow what the owner (Steve Davis) recommends. I use Nosler load data. Start with the starting charge weight and go up in 1 gr increments. Once I hit Nosler max load data, I increase in 0.5 gr increments going 2-3 gr above that published max load. I stop when I find pressure signs. I use a chrono the whole time. Usually a velocity node shows up somewhere within about 1.5 gr of where I hit pressure. Nodes tend to be 0.4-0.8 gr in size. So, I’ll work up in 0.2 gr increments from 1.5 gr of where I hit max to find the best load. Then validate. Usually during load work up, you’ll tend to have a pretty good grouping even though each shot is increasing in charge. If you don’t, change powders. [/QUOTE]
