Tell me how you set seater die when you first use it? The RCBS instructions do not say how to set the seater die plug. I followed the instructions and tried a bullet on a non-charged case to see how it goes and when I brought the shell down the 50gr NBT was in the case. Do I start out with the plug all the way out and then measure and adjust down if I need more seating depth? BTW when I did this I did not make any adj with the plug so that is my problem but how do you start out with the seater plug?
