[QUOTE="Mikecr, post: 1998671, member: 1521"] That is correct. Just like actual tuning results cannot be predicted. Press a thumb against the action tang amidst group shooting, and tell me what that did to the OBT. Nothing right? No entry for that in the calcs. Develop a load off bags filled with sand. Then shoot off bags filled with kitty litter. Why the change in results with the same load, same barrel, and same speed of sound in that barrel? When you adjust bullet seating, the single biggest affect to precision, and impossible to predict, why the results while it's not changing barrel time? A good shooting load can be simplified or complicated. But, it always ends with load development under use conditions, to find the results you're after -wherever they happen to be. [/QUOTE]
