[QUOTE="25WSM, post: 1759901, member: 38048"] The Satterlee load test isn't using SD to find the load. It just shows you the velocity flat spots that are the nodes. I chrono my loads that I do my ladder test with. And the chrono flat spot always is the same as the flat spot on the ladder. Normally in clusters of 3 bullets. Most of my loads are done in 1/3 grain increments. Bigger magnums I do 1/2 grain and anything under 40 grains capacity I do 2/10 grain. My creed will almost always have 4 rounds go flat for a 1.3 grain window. My 300wsm always has a 1.5 or better window. That's why 300wsm is so easy to load for and stays in tune real good. It's a very popular 1000 yard match round. The ladder and the Satterlee doesn't give you your exact load but it gives you the window to start your tweaking from. One other nice aspect of ladders is that you can define what powder is best real easy. There are 3 powders I use for my creed and I shoot a ladder with each. Always one powder will show a much smaller ladder group than the others. That's the powder I try first. Once your all tuned up you can do different primers too. If my load is 45 grains I will take the new primers and load 44.8. 45. And 45.2 and do them at same distance as my ladder and see what is smallest. Shep [/QUOTE]
