Thread: 308 Issues

Yeh, sounds like you have sussed it. Interesting how similar rifles can be different.
To resolve, some just grind a bit off the bottom of the die. I prefer to dick with the shellholder. They are cheap to play with.
What I would do in you case is leave the existing shellholder as it is - it is perfect with your rifle.
Buy another and skim it to suite your son's. You may also find that a new shellholder doesn't have the same issue.
Although shellholders are meant to be made to a standard I have found a lot of variability between brands. The distance to measure is from the shellholder shoulder that sits flat on top of the press ram to the "floor" of the shellholder.

Interesting. I thought it would have been the distance from the top surface of the shell holder to the bottom of the slot for the brass for the minimum/SAAMI standard when the die hits the shell holder. The rest is adjusted from the die position in the top of the press to match the stroke/back off for your chamber.
