[QUOTE="woods, post: 545444, member: 6042"] This thread got me to thinking so I went back through my spreadsheets to find some low ES shot strings. Ran across this seating depth test and decided to run some numbers on ES and SD to see if there was an correlation and input the data onto the target to get a clearer picture [IMG]http://img.photobucket.com/albums/v663/bwestfall/TARGETS/1211-1.jpg[/IMG] These loads were all outside neck turned, neck sized with Lee Collet for .003" bullet grip, new cases, dry lubed with mica, seated with comp seater/comparator, loaded at the same time and shot at the same time. From the data and target it looks like the seating depth of .060" off OR A VELOCITY around 3175 fps would be a node of accuracy and stability. Unfortunately I picked the 3200 fps load and have a bunch loaded because I had not paid attention to ES or SD Time to do more testing [/QUOTE]
