I have the Lee Collet Die set with the dead length bullet seater. I'm using Speer 140 grain Hot Cors with Remington brass for my Ruger M77 Mk II in 6.5x55 Swedish. The seating die is screwed down 1/4 additional turn after the bottom of the die contacts the shell holders, as per the instructions. Length varies around .005, with some going way long as much as .020. Does the seating stem not like the bullets? Speer is the only brand I have tried so far in with these dies.
