I don't know jack about this stuff compared to you guys but, kinda like Roskoe, I was forced into doing this to a degree. I'm cheap...and I'm in college...and I don't shoot enough to justify a "real" press. So the Lee hand press it what I have and by it's very nature the shell is always wiggling around in its seat. It just made sense that I needed to really take my time and let the shell center itself and that naturally progressed to me turning 2-3 times while seating.


Now, I never measured, thought about, or noticed it making any difference. But heck, I'm happy to make minute of deer loads for my revolvers (well, I'll be honest...minute of coke-can) and after fighting 60gr bullets in my 1-14" 22-250 I was happy to get true sub MOA groups out of the 53gr barnes.
