I was looking for a chronograph online today. I really like the Magneto-Speed V3. I went to YouTube to see if there were any videos on the V3. There were a couple videos on useing the Satterlee Load Development method. Has any one here heard of it? If so, do you think it would work with the 450 BM? I'll try to explain it as best I can but would be better to watch videos for yourselves.
You choose the components that you want to test for the caliber of your rifle. With your cases prepped, primed and ready to be loaded. You go to your starting load and load one round. Then you increase powder charge by .2 of a grain. The guys in the video recommended loading ten rounds with the .2 gr. increments. Then shoot them over chrono to find velocities of each round. Wherever you have a plateau in velocity, there is a node or sweet spot. They said there could be more than one node.
I'm thinking of trying it to work up some loads. I thought doing .5 gr. increments. What do you guys think? It sure would save on components and time at the reloading bench.
