KBCraig makes a very good point regarding OAL and bullet setback.
I think it is important to remind folks often about OAL. We need to remember that it is the area under the bullet that defines the pressure. Bullets of different lengths seated to the same OAL will develop different pressures. This is not a big issue for the 9mm and 45acp but it is a huge issue with the 40S&W.
