I cant seem to get this under control. I have used two different seating dies. I am trying to load 223 rem. As suggested, when setting the seating depth, I had a case in the sizing die and still no joy. I put a case in the sizing die, turned out the seating die and put a round in that was exactly 2.260. I turned the seating adjuster in until it touched the bullet then started seating bullets. It varied between 2.245 and 2.276. This is driving me nuts. I also have the shell plate tightened up to where it rotates with a little bit of tension so there is very little to no play at all. Also, when I noticed I was seating to long, I would adjust the depth in and end up with the next one being longer! No that really pissed me off. So what am I doing wrong? I have used a Lee and Lyman die. At the rate I have been going, my Lee turret could keep up with less variance at this point.
