Agreed ^^, two things to check. Check case length, they should be 2.090-2.100.
Set up your seating die according to the instructions. They should read something like this. Place a sized case in the shell holder, raise the ram all the way up, back the seating stem waaaay out of the die, screw the die into the press until you feel it make contact with the sized case, back the die out of the press one full turn and lock the lock ring and set screw. Now adjust OAL with the seating stem.
