[QUOTE="TRG65, post: 1888411, member: 103919"] If you dig up the interview the 6.5 guys do with Scott Satterlee a few years ago, he says it isn't a method you should use unless you are confident in your reloading techniques and capabilities. It is my starting point for load development now. I don't do the 1 shot version that Satterlee talked about, but I use 3 shots and look at the change between and the SD for those loads. A load with a low sd in between charges with poor sd tended to be another indicator of a node. Then I started using the 6.5 guys spreadsheet and it does all the math for you. After I find the node area relying entirely on velocity, then I start looking at seating depth and group sizes to tune. Like someone said before, doing your group size before can be handy, but I've done it both ways and gotten to the same point. Also, I agree with the magnetospeed changing things, so I just shoot for pure velocity and then tune with group testing around the velocity node. Right now I'm going to start working on a 338 WM load. I'm going to try using OnTargetTDS after I do the Satterlee test. I'm also going to test neck tension with the on target software. [/QUOTE]
